What Atmos is

Atmos is a color palette tool for UI designers, available as a web app and extension. Its generator, color wheel, shade generator, and playground help users create and refine palettes. The playground supports color spaces such as LCH and OKLCH, with gamut limits including sRGB and Display P3. Its contrast checker supports APCA (WCAG 3) and WCAG 2.

Users can save palettes, keep a brand color library, and share palettes with teammates for collaboration. Export options include SVG, Figma, CSS, JavaScript, JSON, Tailwind CSS, Style Dictionary, Design Tokens, and Raw; supported color formats include HEX, HSL, RGB, CMYK, LCH, and OKLCH. Atmos also offers a Figma plugin, while Pro adds palette syncing with Figma. The free plan allows one project; Pro provides unlimited projects and access to all features. A 14-day free trial does not require a credit card, but trial exports are limited to SVG. Atmos is built and hosted in the European Union and is made by RBND studio, a small team of designers and developers.
