About Color Picker
Every designer and developer needs a reliable color picker that converts between formats instantly. This tool combines a visual HSL color canvas with real-time conversion to HEX, RGB, HSL, and CMYK — plus automatic palette generation for design inspiration.
How It Works
The picker uses the HSL color model internally (Hue 0-360°, Saturation 0-100%, Lightness 0-100%) for intuitive color selection, then converts mathematically to all other formats in real time. Palettes are generated using color theory relationships on the hue wheel.
Who Is This For
A frontend developer needs to convert a designer's HEX color to RGB for a canvas drawing context — types #3b82f6 and gets rgb(59, 130, 246) instantly.
A designer exploring color schemes picks a brand blue, then uses the generated triadic palette to find complementary accent colors.
A developer debugging CSS sees rgb(34, 197, 94) in DevTools and needs the HEX equivalent — the tool converts it instantly.
A print designer converting screen colors to CMYK for a brochure — picks the color and reads the CMYK values directly.
Scope note: CMYK conversion is approximate (uses a standard formula without ICC color profiles). For print-accurate CMYK, verify with professional color management software.
