PALETTEUI
Color, clarified — palette generators, contrast checkers, and the color tools every designer needs.
From generating a harmonious palette and checking WCAG contrast to converting HEX, RGB, and HSL, simulating color blindness, building gradients, and naming a color, PaletteUI pairs free hands-on color tools with practical design guides and a richly illustrated color museum. Design smarter, see clearer.
Color Tools & Calculators
Free tools for working with color — WCAG contrast ratio, hex-to-RGB and RGB-to-hex, tint and shade builders, and an alpha-blend preview.
Contrast Ratio Calculator
Check the WCAG contrast ratio between two colors' luminances — the number that decides whether text is readable and your UI passes AA and AAA accessibility
Hex to RGB Converter
Turn a hex color code into its red, green, and blue channel values — the everyday conversion for moving a brand color between design tools and CSS
RGB to Hex Converter
Convert red, green, and blue channel values into a clean hex code — paste from a color picker and get the string your stylesheet needs
Tint Calculator
Mix a color toward white by any percentage to build a lighter tint — generate the soft, airy steps of a palette from a single base color
Shade Calculator
Darken a color toward black by any percentage to build a deeper shade — round out a palette with rich, grounded tones from one starting color
Alpha Blend Calculator
See the flat color a semi-transparent layer produces over a background — predict exactly what an overlay or tint at a given opacity will look like
The Color Museum
Wander an illustrated museum of color — the theory of the color wheel and harmony, the models and systems from RGB to Pantone, the meaning and psychology of individual colors, and the storied pigments and dyes from ultramarine to Tyrian purple, each in its own gallery, drawn entirely from Wikipedia and Wikimedia Commons.
