What Atmos is
Atmos is a color palette tool for UI designers, offered as a web app and extension. It includes a color generator, color wheel, shade generator, and playground for creating and refining palettes. The playground supports LCH and OKLCH color spaces plus sRGB and Display P3 gamut limits. Its contrast checker covers APCA (WCAG 3) and WCAG 2. Users can save palettes, maintain a brand color library, share palettes with teammates, and collaborate. Export formats include SVG, Figma, CSS, JavaScript, JSON, Tailwind CSS, Style Dictionary, Design Tokens, and Raw, with color values available in HEX, HSL, RGB, CMYK, LCH, and OKLCH. Atmos has a Figma plugin, while Pro adds palette syncing with Figma, unlimited projects, version history, all export formats, shareable palettes, and no ads. The free plan allows one project. A 14-day trial requires no credit card but limits exports to SVG. After downgrading, palettes remain viewable and exportable to SVG but cannot be edited. Atmos is made by RBND studio and hosted in the European Union.
