How to choose a color palette tool
What to look for
Palette tools differ more in workflow than in the colors they produce, so start with what you need to do with the result. A brand designer exploring ideas and a developer shipping a theme need different things. These are the criteria that tend to matter, and they are the ones we use on the Coolors and Adobe Color comparison pages.
Color space
A tool that works in HSL or plain RGB can make two colors of the same nominal lightness look very different. A perceptual space such as OKLCH keeps lightness and chroma more even, which helps when you generate a ramp or a set of brand hues that should feel balanced. If you only need a handful of swatches the space matters less, but for design systems it saves a lot of manual correction. See the OKLCH vs HSL guide for the details.
Accessibility checks
Look for a contrast check against WCAG 2.2 (4.5:1 for normal text, 3:1 for large text and components at level AA), and ideally APCA as a second signal. A tool that checks contrast while you pick saves a round trip. Also check for a color-blindness preview, which shows how a palette looks with common types of color vision deficiency, because colors that differ only in red versus green are easy to confuse. Our own contrast checker covers WCAG and APCA, and the WCAG vs APCA guide explains the difference.
Exports and integrations
Check that the tool exports what your workflow consumes: CSS variables, a Tailwind theme, W3C DTCG design tokens for a token pipeline, or a plugin and library format for a design app such as Figma or the Adobe apps. Some tools are strongest at keeping swatches in sync inside a design environment, and others are strongest at producing code. Neither is better in general; it depends on where your colors end up. For programmatic access, check whether there is an API, and whether it can be used by AI agents, for instance through MCP. Ours is described on the developers page.
Inspiration and reference
Some tools are mostly a source of ready-made palettes, others mostly a place to build your own. A large library helps when you are looking for a starting point by mood or theme, while reference pages for individual colors help when you already have a value and want its name, conversions and accessible text colors. Try both styles against a real project, such as a landing page or an app theme, before committing, because a tool that looks great for a moodboard can be awkward when you need exact values for a design system. Our palette library and color pages cover both of those needs.
Pricing, signup and saving
Many tools are free to use but ask for an account to save palettes, or limit some features to a paid plan. Pricing changes, so check the vendor's current page and not an old comparison. Think about whether you need cloud-saved libraries and team sharing, which usually need an account, or whether you just want to pick, check and copy. Colorise Pro needs no signup, which also means it has no cloud sync or team features.
An honest summary of the two comparisons
Coolors is a polished palette generator with a fast generate-and-lock workflow, a Figma plugin and saved palettes on an account. If that is how you work, it is a good fit, and Colorise Pro does not replace it. Colorise Pro is better when you want OKLCH, WCAG and APCA checks and Tailwind, CSS or DTCG export without an account. The full table is on the Colorise Pro vs Coolors page.
Adobe Color is strong on classic color-wheel harmony rules, image themes and Creative Cloud Libraries that sync with Adobe apps, so it suits work that lives in Photoshop or Illustrator. Colorise Pro fits better if your colors end up in CSS or design tokens. Details are on the Colorise Pro vs Adobe Color page. To try our tools yourself, start with the picker or the palette library.
