ChromaKit - Color Picker

Sample any color from a photo with a pixel-precise loupe, then check it against WCAG contrast standards. No account, no cloud — everything stays on your device.

ChromaKit is a precision color tool for designers, developers, and anyone who works with color.

SAMPLE WITH PRECISION Load a photo and press and drag to sample any pixel. A magnifier loupe zooms in so you pick the exact pixel you mean — not the one your fingertip happened to cover. Every color reads out as hex, RGB, and HSL, with an approximate color name and hue family.

CHECK ACCESSIBILITY CONTRAST — FREE Compare any two colors against WCAG 2.1. See the contrast ratio and instant AA / AAA pass or fail for both normal and large text, using colors sampled from the real world — signage, screens, print — not just ones you type in.

EXPLORE COLOR HARMONIES See complementary, analogous, and triadic suggestions for any color, and tap through to inspect each one.

EXTRACT AND SAVE PALETTES Pull the dominant colors out of any photo, save and name your palettes, and revisit them anytime.

PREVIEW FOR COLOR BLINDNESS See how a palette looks with protanopia, deuteranopia, or tritanopia, and build designs that work for everyone.

EXPORT ANYWHERE Share any palette as JSON, CSS variables, or a PNG swatch sheet format.

PRIVATE BY DESIGN No account. No sign-in. No tracking. No cloud. Your photos never leave your device, and your palettes are stored only on your phone.

FREE AND PAID Color sampling, the contrast checker, harmonies, and color history are free. A single one-time purchase — no subscription — unlocks saving palettes, the palette library, export, and the colorblindness preview.
