About Atmos
Atmos is a set of browser tools for building interface color palettes. It includes a color generator and a color wheel with complementary, triadic, tetradic and analogous modes, which can be viewed side by side. The wheel angles can be adjusted.
It also generates success, warning, danger and info colors from a primary color. Other tools create uniform shades and color scales, and a playground previews the result. Accessibility checks are part of the workflow. Atmos can be tried for free, and there is an account login.
