3 Color Palette Generator Tools, Compared Honestly
Heshan Fernando
Co-founder & COO
You’ve got a base color — or none at all — and need a harmonious set of colors for a design, a website, or a brand mood board.
A lot of palette generators are excellent tools that have grown into full design platforms: browsing millions of community palettes, previewing on mockups, extracting colors from photos. Useful, but more than a quick “give me five colors that work together” needs.
How to judge a color palette generator tool
Uses real color theory. Complementary, analogous, triadic, and monochromatic schemes should be based on actual color relationships, not arbitrary variation.
Starts from your color. You should be able to lock in a base color and build the palette around it, not just get random results.
No signup for a quick palette. Generating and viewing hex codes shouldn’t require an account.
Shows hex codes clearly. You need to copy exact values, not just eyeball colors on screen.
The comparison
| Tool | Best for | Free tier | Watch out |
|---|---|---|---|
| Coolors | Spacebar generation, image color extraction | Free, no signup for core tools | Ads shown unless you disable your ad blocker or subscribe |
| Paletton | Monochromatic through tetrad schemes with fine control | Free | Site relies on ad revenue, asks visitors not to block ads |
| Adobe Color | Built-in accessibility and color-blindness checks | Free to generate | Saving palettes typically needs an Adobe account |
| Color Palette Generator | Fast 5-color harmony from any base color | Free, no signup | No image color extraction or accessibility checker built in |

Coolors
Coolors lets you generate palettes instantly by hitting the spacebar, extract colors from an uploaded image, check contrast for accessibility, and browse over 10 million existing palettes — all without an account for the core tools.
It isn’t for someone who wants an ad-free experience without paying — the site relies on ads to stay free, with a $3/month Pro tier removing them and unlocking unlimited saves.
Paletton
Paletton covers a wide range of color schemes from monochromatic to triad and tetrad sets, with adjustable brightness and saturation and a randomize option for quick exploration.
It isn’t for someone who wants a completely ad-free page — the site is explicit that advertising is its only revenue source and asks visitors to allow ads or donate instead.
Adobe Color
Adobe Color supports monochromatic, complementary, analogous, triadic, and split-complementary harmonies, plus built-in WCAG contrast checking and color-blindness simulation — useful if accessibility is part of your design process from the start.
It isn’t for someone who wants to save their palette without any account — saving and organizing palettes for later typically requires signing in with an Adobe ID.
Color Palette Generator
Our tool generates a harmonious 5-color palette from any base color using monochromatic, analogous, complementary, triadic, or split-complementary color theory, entirely in your browser.
A real limitation: there’s no image-based color extraction or built-in accessibility checker — for those, you’d pair it with a dedicated contrast-checking tool.
Which one to pick
If you want a fast 5-color palette from a base color with no ads or signup, use our Color Palette Generator.
If you want to extract colors from an existing photo or image, use Coolors.
If you want fine-grained control over brightness and saturation across a wide range of scheme types, use Paletton.
If accessibility checking matters as part of your palette-building process, use Adobe Color.
How to do it with Color Palette Generator
- Open the Color Palette Generator.
- Pick a base color, or start from a default.
- Choose a harmony type — monochromatic, analogous, complementary, triadic, or split-complementary — and copy the resulting hex codes.

A palette that looks good doesn’t always meet accessibility standards for text readability. Our Contrast Ratio Checker checks the WCAG contrast ratio between any text and background color pair, with live pass/fail results for AA and AAA.
Frequently asked questions
Is there a free color palette generator that doesn’t need an account?
Yes. Our Color Palette Generator and two of the three alternatives here generate palettes without an account — Adobe Color typically needs one only if you want to save your result.
What’s the difference between complementary and analogous color schemes?
Complementary colors sit opposite each other on the color wheel, creating high contrast and visual energy. Analogous colors sit next to each other, creating a more harmonious, low-contrast feel — the choice depends on whether you want a design to pop or feel cohesive.
How many colors should a design palette have?
There’s no fixed rule, but five colors is a common sweet spot — enough for a primary, secondary, accent, and two neutrals, without so many that consistency becomes hard to maintain. Design references like Material Design’s color system build out from a similarly small core set.
Final thought
For a quick palette to start a design, pick the tool that gets you from a base color to five usable hex codes fastest — save the image extraction and accessibility auditing for the point in your process where you actually need them.
