Best color tools at a glance
Pick the task, then open the tool. Each is free and needs no account.

|---|---|---|

Pick and convert colors
Start with the color itself. Colour Picker lets you choose a shade and copy its hex code, and Color Converter translates one color between hex, RGB, and HSL. For the two formats used most on the web, Hex to RGB and RGB to Hex convert both ways in a click.
Build and extract palettes
To design a coordinated set of colors, Colour Palette Generator builds a palette you can tweak. To borrow colors from an image, Colour Palette Extractor and Extract WebP Color Palette pull the main shades as hex codes, and Image to RGB Values lists the raw values.
Accessibility and contrast
Color choices affect who can read your work. Colour Contrast Checker tests a text and background pair against the WCAG accessibility levels, and Colour Blindness Simulator previews how a design looks to people with different kinds of color blindness, so you can fix problems before publishing.
Color and recolor images
Some color tools work on whole images. Change Image Base Color recolors a picture, Image to Web Safe Colors maps it to the classic web palette, and Image to Color Mosaic turns it into blocks. To make solid swatches, Create Image With One Color and Create Two Color Image generate plain backgrounds, and Extract Object By Color isolates a colored region.
How to choose the right tool
Match the tool to the need. Grabbing or converting one color is the picker or converter. Designing a set is the palette generator, and borrowing from a photo is the extractor. Making sure text is readable is the contrast checker and the colorblind simulator. Working on a whole picture is one of the image color tools. Each is a single focused tool, so the result is one step away.
Trusted alternatives
For palette inspiration, Adobe Color and Coolors are popular free sites. The eyedropper in your browser developer tools or operating system grabs any on screen color, and a design app like Figma has color tools built in. For a single quick pick, conversion, or contrast check, a focused browser tool is faster.
