Free Color Tools for Designers and Marketers
These tools handle the colour work that eats your afternoon: converting a hex code a developer sent you, pulling a palette out of a client photo, checking whether your brand blue is actually readable, and building tints and shades without opening design software. Everything runs in your browser, nothing gets uploaded, and there's no account to create. Pick the one you need and get on with the actual job.
What free color tools does IWantFreeColorTools offer?
IWantFreeColorTools offers ten free browser-based colour tools in three groups: converters for HEX, RGB, HSL and CMYK, plus CSS colour names and colour mixing; pickers and palette builders including a gradient generator, image colour picker, tint and shade generator and random colour generator; and a WCAG accessibility contrast checker. A brand colour quiz recommends a palette for your business.

1 toolWorth running before a palette ships rather than after. WebAIM's 2026 audit of the top one million home pages found low contrast text on 83.9% of them, making it the most common accessibility failure on the web.

Take QuizWhich Tool Should You Reach For?
If you're starting from nothing, take the brand colour quiz and treat what it gives you as a first draft. Then run the primary through the tint and shade generator to build out the light and dark variants you'll need for hover states, borders and disabled controls. One brand colour is never enough in practice.
If you're starting from an image, whether that's a client's photography or a product shot, use the image colour picker to lift the real colours out of it rather than guessing at them by eye. Screens shift colour more than people expect, and eyeballing a hex from a photo is usually a couple of steps off.
If you already have a palette and just need to check it, go straight to the accessibility checker. It handles the case most contrast tools skip: buttons, borders and icons are covered by a different WCAG criterion at a lower 3:1 threshold, and holding them to the 4.5:1 text rule makes designers change things that were already fine.
And if you want the reasoning rather than the tool, the blog covers colour theory, palette building, accessibility and brand colour in more depth. The brand colour palette guide and the WCAG accessibility guide are the two that pair most directly with the tools on this page.
