About this tool
Pick, parse, and validate colors for design systems, CSS, branding, and UI work while keeping alpha and contrast assumptions visible.
Color Picker is the fastest option when you want to grab a color visually and immediately copy it in a format that works for design or frontend work. It is less about conversion theory and more about moving from a swatch to usable values quickly.
- Accepts 3, 4, 6, or 8 digit HEX plus comma- or space-separated RGB(A) and HSL(A), including percentage alpha and common hue units.
- Keeps alpha across HEX8, RGBA, and HSLA output and calculates WCAG contrast after compositing the foreground over an opaque background.
- Provides individually named copy controls for HEX, RGB, HSL, and CSS custom-property output.
- Keeps up to eight committed colors in session-only recent swatches without storing them after refresh.
How to use Color Picker
Pick a color with the browser control or type a HEX value directly, then copy the matching HEX, RGB, or HSL values from the result cards. Use the built-in contrast check before applying the color to readable interface text.
When this tool is useful
- Grab a color visually during UI implementation or design handoff.
- Check brand swatches quickly before converting them into CSS variables or design tokens.
- Compare one picked color across HEX, RGB, and HSL formats without leaving the browser.
Practical tips
- Use HEX for quick CSS references and HSL when you want to make tone adjustments later.
- Check the contrast ratio before using a picked color on text, buttons, or status badges.
- Keep one approved brand swatch nearby so ad hoc color edits do not drift over time.
Examples you can test
Load an example, compare the result with the expected output, then replace it with your own input.
Pick a UI accent color
Example input
Selected color: teal
Expected output
HEX, RGB, and HSL values
Useful when copying a color into CSS, design tokens, or documentation.
Compare color formats
Example input
#0f766e
Expected output
RGB and HSL equivalents
Different workflows prefer different formats, so having all values reduces manual conversion.
Validation checklist
- Check text contrast before using a color for readable UI copy.
- Keep brand colors documented in one source of truth.
- Review colors in light and dark contexts when the UI supports themes.
