Picking colors by gut feeling works until you’re staring at a hero section that looks like a bag of Skittles threw up on it. I’ve been there more than once.
I spent the last month testing every free color palette generator I could find – around 20 tools total – to figure out which ones actually produce usable palettes without forcing you into a paid plan. Some of these tools are genuinely good. A few are borderline scams with paywalls hiding behind “free” labels.
Here’s what I landed on after testing them on real projects: two client websites, a mobile app concept, and a rebrand for a side project.
| Tool | Best For | Image Extraction | Export Formats | Free Tier Limits |
|---|---|---|---|---|
| Coolors | Quick palette generation | Yes | PNG, PDF, SVG, CSS, SCSS | 5 saved palettes, ads |
| Adobe Color | Advanced harmony rules | Yes (best) | ASE, CSS, link share | Unlimited with free Adobe account |
| Realtime Colors | Web design preview | No | CSS, Tailwind, Figma plugin | Fully free, no account needed |

| Color Hunt | Browsing curated palettes | No | Hex codes (copy) | Fully free |
| Canva Color Palette Generator | Image-based extraction | Yes | Hex codes | Fully free |
| Khroma | AI-personalized colors | No | Hex, RGB (copy) | Fully free |
| Muzli Colors | Quick inspiration | No | Hex codes, URL share | Fully free |
1. Coolors – Best Overall Free Palette Generator
Coolors is the tool I reach for first. Hit spacebar, get a new palette. That’s it. The simplicity is the whole point.
But underneath the simple interface there’s a lot going on. You can lock individual colors, adjust hue/saturation/brightness with sliders, check contrast ratios between any two colors, and simulate how your palette looks to people with different types of color blindness (protanopia, deuteranopia, tritanopia).
The image extraction feature pulled accurate palettes from every photo I tested. I uploaded a sunset shot and got five colors that actually matched what I saw, not some weird algorithmic interpretation.
Export options cover most workflows: PNG for presentations, SVG for design files, CSS variables for developers, and even SCSS if you’re still writing Sass (no judgment). You can also generate palette variations – complementary, analogous, triadic – from any starting color.
What’s behind the paywall
Free accounts are limited to 5 saved palettes. You see ads. The paid plan ($3/month) removes ads and unlocks unlimited saves, plus features like recoloring SVGs and generating gradients. Honestly, 5 saved palettes is plenty if you just export what you need and don’t use Coolors as a storage system.
Pros
- Spacebar generation makes browsing palettes almost addictive
- Built-in accessibility checker (contrast + color blindness simulation)
- Export to CSS, SCSS, SVG, PNG, PDF
- Accurate image color extraction
Cons
- 5 saved palettes on free plan
- Ads on the free version
2. Adobe Color – Best for Color Theory Nerds
If you actually want to understand why certain colors work together, Adobe Color is where you should be spending your time. The color wheel interface lets you pick harmony rules – analogous, monochromatic, triad, complementary, split-complementary, double split-complementary, square, compound, shades – and then drag points around the wheel to see how everything shifts.
The image extraction here is the best I tested. Upload a photo and you get options: colorful, bright, muted, deep, dark, or custom. Each mode pulls a completely different palette from the same image. I uploaded a forest photo and the “muted” extraction gave me a palette I used directly on a client project without any tweaking.
Adobe Color also has an accessibility panel that checks your palette against WCAG 2.1 guidelines. It flags which color combinations fail contrast requirements and suggests fixes. This alone makes it worth using if you build anything that needs to be accessible (which, look, should be everything).
The explore section has thousands of community palettes you can search by mood, keyword, or color. Found some great inspiration browsing “nordic” and “brutalist” tags.
Free tier details
You need a free Adobe account, but you don’t need a Creative Cloud subscription. Everything I described above works on the free tier. If you have a CC subscription, palettes sync to your Libraries in Photoshop, Illustrator, and other Adobe apps, which is convenient but not necessary.
Pros
- Best image extraction with multiple extraction modes
- Full color harmony rules on an interactive wheel
- WCAG accessibility checking built in
- Community palette library with search
- Free with just an Adobe account
Cons
- Interface feels complex at first
- Library sync only works with paid CC subscription
3. Realtime Colors – Best for Web Designers
This one is a different beast. Instead of showing you colored squares, Realtime Colors shows your palette on an actual website layout. You pick your text color, background, primary, secondary, and accent colors, and you immediately see them applied to headings, buttons, cards, navigation, and body text.
That changes the game. I can’t tell you how many times I’ve picked a palette that looked gorgeous as five squares in a row and then looked terrible on a real page. Dark navy background with light blue text? Beautiful in a palette strip. Unreadable on screen at 16px.
Realtime Colors eliminates that disconnect. You see the problem before you commit to it.
The tool generates CSS custom properties, Tailwind config values, or a Figma plugin export. There’s also font pairing built in – pick your heading and body fonts and see those applied to the preview too. No account required, nothing to save (you get a shareable URL instead).
Pros
- See palette on a live website mockup instantly
- Export to CSS variables, Tailwind, or Figma
- Font pairing built in
- Completely free, no account needed
- Shareable URLs for client reviews
Cons
- Only one website template layout
- No image extraction
- Limited to 5 color roles (text, background, primary, secondary, accent)
4. Paletton – Best for Learning Color Theory
Paletton has been around since the early 2000s and the design shows it. But here’s the thing – the functionality underneath that dated interface is solid. Really solid.
The color wheel gives you real-time visualization of your palette applied to a sample web page, similar to Realtime Colors but with more emphasis on the color relationships. You can fine-tune the distance between complementary colors, adjust the angle of your triadic selection, and see exactly how the math behind color harmony works.
I found Paletton most useful when I was trying to explain color theory to a junior designer on my team. The way it shows the geometric relationships on the wheel made the concepts click for her in about 10 minutes.
Export options are decent: CSS, XML for Android development, plain text, and PNG preview images. Everything is free. No accounts, no limits, no paywalls. The developer seems to run it as a passion project.
Pros
- Excellent color theory visualization
- Sample website preview with your colors
- Fine-tuned control over harmony angles
- 100% free, no account, no ads
Cons
- Outdated interface design
- No image extraction
- Mobile experience is rough
5. Color Hunt – Best for Quick Palette Browsing
Sometimes you don’t want to generate colors. You just want to scroll through a feed of palettes and grab one that catches your eye. That’s Color Hunt.
The site is essentially a curated collection of four-color palettes, sortable by popularity, newness, or category (pastel, vintage, neon, earth, etc.). Community members submit palettes and the best ones get upvoted. The popular section is genuinely useful – these are palettes that thousands of designers have validated.
Click any color in a palette and the hex code copies to your clipboard. That’s the entire interaction. No bells, no whistles, no accounts.
I used Color Hunt when I was stuck on a mood board for a branding project. Scrolled through the “warm” category for about 5 minutes, found a palette with 12,000 likes, adjusted one color slightly in a design tool, and the client approved it on the first round. Sometimes the shortcut works.
Pros
- Massive curated palette library
- Community upvoting surfaces the best options
- One-click hex code copying
- No account needed
- Categories and trending palettes
Cons
- Only four colors per palette
- No generation tools – browse only
- No export beyond copying hex codes
6. Canva Color Palette Generator – Best Image Extraction for Non-Designers
If you already use Canva (and statistically, you probably do – they have over 190 million monthly users), the Color Palette Generator is tucked into their website.
Upload any image, get a palette of 4-5 dominant colors. The extraction is accurate and the results display with hex codes you can copy individually. Dead simple.
Where Canva beats competitors on extraction: the colors feed directly into Canva’s design tools. Build a presentation using the palette you just extracted from your company’s hero image. Brand consistency with zero effort. If you’re making social media graphics or slide decks – and you’re not a professional designer – this workflow saves real time. Maybe 20 minutes per project compared to manually copying hex codes between tools.
It won’t give you the extraction modes that Adobe Color offers (muted, bright, deep, etc.), and it only extracts from images. No color wheel, no harmony rules, no generation from scratch. But for the specific use case of “I have a photo and I need matching colors,” it works well.
Pros
- Integrates directly with Canva’s design tools
- Clean, simple interface
- Accurate image extraction
- Free, no Canva Pro needed
Cons
- Image extraction only, no generation
- Limited to 4-5 colors per extraction
- No export options beyond hex codes
7. Khroma – Best AI-Powered Palette Generator
Khroma takes a different approach. When you first visit, it asks you to pick 50 colors you like from a grid. Takes about 2 minutes. Then its AI trains on your preferences and generates endless palettes tailored to your taste.
I was skeptical. “AI picks colors” sounds like marketing fluff. But after going through the training process, the palettes it generated were consistently in my wheelhouse. It learned that I gravitate toward muted blues, warm grays, and occasional pops of coral. The suggestions reflected that.
You can view results as typography pairings, gradient previews, poster mockups, or simple color blocks. The typography view is especially useful – it shows your palette as actual text on a background, so you can immediately gauge readability.
Search functionality lets you filter by hue, tint, value, or specific hex ranges. I filtered to “blues between #2a4365 and #4a90d9” and got 30+ variations ranked by how well they matched my trained preferences. That specificity is hard to find in other tools.
Pros
- AI personalizes output to your actual taste
- Multiple preview modes (typography, gradients, posters)
- Powerful search and filter options
- Infinite generation after training
- Completely free
Cons
- Initial 50-color training takes a couple minutes
- No image extraction
- Limited export (copy hex/RGB values)
8. Muzli Colors – Best for Fast Inspiration
Muzli Colors (by InVision, now part of the larger design community) is a lightweight palette generator that shows your colors applied to a UI mockup. Pick two colors and the tool generates a full palette plus shows how those colors look on buttons, cards, and navigation elements.
The two-color input is actually clever. Most palette generators ask you to choose 5 colors and hope they work together. Muzli asks for 2 and figures out the rest. For someone who knows their brand’s primary and secondary colors but struggles with supporting colors, that’s a real time-saver.
I used it during a quick redesign sprint when I had a primary purple (#6C63FF) and a dark background (#1a1a2e) and needed accent colors fast. Plugged them in, got three suggestions for accents, grabbed the one that worked, and moved on. Total time: about 90 seconds.
The UI preview is less detailed than Realtime Colors but loads faster and requires zero configuration. Good for a quick gut check.
Pros
- Two-color input generates complete palettes
- UI mockup preview included
- Fast and lightweight
- No account needed
Cons
- Less control over generation rules
- No image extraction
- UI preview is basic compared to Realtime Colors
How I Tested These Tools
I ran each tool through the same four tests:
Test 1: Generate a palette from scratch for a SaaS landing page. I needed a professional look with a blue primary. I checked whether the tool could get me from “I want blue” to a usable 5-color palette in under 2 minutes.
Test 2: Extract colors from a product photo. I used the same stock photo of a coffee shop interior across all tools that support image extraction. Compared the extracted palettes for accuracy and usefulness.
Test 3: Check accessibility. I tested whether each tool could tell me if my text/background combinations met WCAG AA contrast requirements (4.5:1 ratio for normal text).
Test 4: Export to a usable format. Could I get CSS variables, a shareable link, or at minimum copyable hex codes without jumping through hoops?
Coolors and Adobe Color passed all four. Realtime Colors and Paletton passed three (no image extraction). Color Hunt, Canva, Khroma, and Muzli each passed two.
Quick Tips for Building Better Palettes
After years of picking colors for web projects, here’s what I’ve learned works:
Start with your text and background. Not your brand color. Not your accent. Your text and background determine 90% of how your site feels. Get those right first, then add personality with accent colors.
Test on real content. A palette that looks beautiful on a marketing landing page can look awful on a dense dashboard. If you’re building a data-heavy app, test your palette with tables and charts, not just hero sections.
Use fewer colors than you think you need. Four core colors plus their tints and shades will handle most interfaces. Every additional color increases the chance that something will clash.
Check contrast on mobile. Phone screens in direct sunlight eat low-contrast designs alive. What passes WCAG on your calibrated monitor might fail in real-world conditions. Bump your contrast a notch higher than the minimum requirement.
If you’re building a website from scratch, picking the right palette early saves hours of redesign work later. Same goes for creating a logo – your palette should be locked before you start.
Which Color Palette Generator Should You Pick?
For most people, Coolors is the right starting point. It’s fast, the free tier is adequate, and it covers generation, extraction, and accessibility checking in one place.
If you need to understand color relationships for design education or client presentations, Adobe Color gives you more depth.
If you’re a web developer who wants to see colors in context before writing any CSS, Realtime Colors will save you from the “palette looked great in isolation” trap.
And if you just want to grab a proven palette and move on with your life, Color Hunt gets you there fastest.
Not gonna lie, I use all four depending on the situation. They’re free. There’s no reason to commit to just one.
FAQ
What is the best free color palette generator?
Coolors is the best overall free color palette generator for most users. It generates harmonious palettes with one tap, supports color blindness simulation, and exports to multiple formats. The free tier is generous enough for most design work.
Can I extract a color palette from an image for free?
Yes. Adobe Color, Coolors, and Canva Color Palette Generator all let you upload an image and extract colors from it at no cost. Adobe Color gives you the most control over extraction rules (colorful, muted, deep, etc.).
What color palette generator works best for web design?
Realtime Colors is purpose-built for web design. It shows your chosen palette applied to a live website mockup in real time, so you can immediately see how your colors look on buttons, backgrounds, text, and cards.
Are there color palette generators that check accessibility?
Yes. Coolors includes a contrast checker and color blindness simulator. Adobe Color has a full accessibility panel that flags WCAG compliance issues. Colour Contrast Analyser (by TPGi) is a free standalone desktop tool specifically for accessibility testing.
How many colors should a design palette have?
Most design systems use 4 to 6 core colors: a primary, a secondary, one or two accent colors, a background, and a text color. You can extend with tints and shades, but keeping the base palette small prevents visual chaos. If you’re working on photo editing or illustration, you might use more, but for UI and web, keep it tight.
