Atmos

Atmos is a colour palette tool for UI designers from RBND studio, pairing a colour wheel and generator with a shade generator that builds uniform scales using easing curves and hue shifts. It works in perceptual colour spaces such as LCH and OKLCH, respects gamut limits like sRGB and Display P3, and includes a contrast checker, a vision simulator, version history and a Figma plugin. It suits design system teams building colour scales that need to be consistent and accessible.
