About the Color Picker & Eyedropper

A free online color picker and eyedropper for developers and designers. Pick any color, convert it between HEX, RGB, RGBA, HSL, HSLA and HSV, check WCAG contrast, build palettes, and export CSS — right in your browser.

What this tool does

This color picker lets you choose a color with a saturation/brightness square, hue and alpha sliders, or by typing a HEX value — then copy it in any format with one click. Use the built-in eyedropper to grab any color from your screen, generate tints, shades and harmonies, check accessibility contrast, and export a full palette as CSS variables or JSON. Everything runs locally in your browser; nothing is uploaded.

Key features

Made for real front-end and design work:

  • Eyedropper: sample any pixel on screen using the native EyeDropper API (Chrome/Edge 95+).
  • Every format, one-click copy: HEX, RGB, RGBA, HSL, HSLA, HSV, and a CSS custom-property snippet.
  • Full alpha/transparency support across all formats.
  • Recent colors (last 20) and a saveable, nameable palette — stored locally in your browser.
  • Shades, tints, and harmony suggestions: complementary, analogous, and triadic.
  • WCAG contrast checker with AA/AAA pass-fail for normal and large text.
  • Export your palette as CSS variables or JSON.

How to use it

Drag inside the color square or type a HEX code, then adjust hue and opacity with the sliders. Click any format card to copy it. Use the eyedropper to lift a color from an image or design. Save colors you like to your palette, generate shades and harmonies, verify contrast for accessible text, and export when you're done.

Why it matters for SEO and UX

Consistent, accessible color choices improve readability and user experience — signals that support engagement and on-page quality. The contrast checker helps you meet WCAG AA/AAA so your text stays legible for everyone, and exporting design tokens keeps your styling consistent across pages.

Pro tip

Pair the Color Picker with the HEX to RGB and RGB to HEX converters for quick one-off conversions, and use the contrast checker before finalizing your text and button colors.

FAQ

Is the Color Picker free to use?
Yes. It's completely free, needs no account, and runs entirely in your browser.
How does the eyedropper work?
It uses your browser's native EyeDropper API to sample any pixel on your screen. Click the eyedropper button, then click anywhere to capture that color. It works in Chrome and Edge 95+; on unsupported browsers you can still use the manual picker and HEX field.
Which color formats are supported?
HEX, RGB, RGBA, HSL, HSLA, HSV, and a ready-to-paste CSS custom property — each with one-click copy. Alpha/transparency is supported across all of them.
Do you store my colors or data?
No. Your recent colors and saved palette are stored only in your own browser via local storage. Nothing is uploaded to our servers, and there are no network calls or tracking.
What is a good WCAG contrast ratio?
For normal text, aim for at least 4.5:1 to pass AA and 7:1 to pass AAA. For large text (about 18pt or 14pt bold), 3:1 passes AA and 4.5:1 passes AAA. The tool shows all four results as you edit the colors.
How do shades, tints, and harmonies work?
Tints mix your color toward white, shades mix it toward black, and harmonies rotate the hue to suggest complementary (180°), analogous (±30°), and triadic (120°/240°) colors. Click any swatch to copy or use it.
Can I export my palette?
Yes. The Export tab outputs your saved palette as CSS variables (:root custom properties) and as JSON, each with a one-click copy button.
Does it work on mobile?
Yes. The layout is responsive. The eyedropper is a desktop-browser feature, but the manual picker, formats, palette, contrast checker, and export all work on phones and tablets.
Is there a Chrome extension version?
Yes — we also publish a free Color Picker & Eyedropper Chrome extension with the same features so you can pick colors from any page without opening the tool.
