Design for everyone
Accessibility, before it ships
Built-in WCAG contrast checking and live colour-blindness simulation for protanopia, deuteranopia, and tritanopia, so accessibility problems surface before they ship.
Palettes that work
Harmony, generated for you
Automatic harmony suggestions: complementary, analogous, triadic, and tetradic, with tints, shades, and tones. Generate palettes or pull them straight from a photo.
Mix like the real world
Three ways to blend
Blend two colours as light (RGB), as ink (CMYK), or the way the eye sees it (LAB).
Your own spectrum
A library that becomes a ribbon
Save, tag, and search your colours, then watch your library flow into one continuous hue-sorted ribbon that grows as you collect.
Learn the science
Six chapters of colour
Six chapters covering light, gamuts, perception, harmony, professional colour management, and accessibility.
