Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

Atmos is a web-based color palette tool for designers and developers building UI color systems. It covers brand and semantic color generation, color-wheel harmony schemes, perceptually uniform shades and tints, and editing in LCH and OKLCH. Teams can also import HEX, RGB, HSL, CSS, and JSON values, save palettes, review contrast, simulate color-vision differences, and share palette work.

Its strongest fit is structured design-token work. Atmos can generate shades using WCAG contrast requirements and supports accessibility checks alongside perceptual editing, which gives teams more control than a palette generator focused only on visual harmony. The export range includes SVG, Figma, CSS, JavaScript, JSON, Tailwind CSS, Style Dictionary, Design Tokens, and Raw formats. Figma synchronization adds a direct path from palette development to a design workflow, while version history and shareable palettes support ongoing collaboration.

Atmos is a paid web product with a 14-day trial rather than a perpetual free plan. The Pro plan includes unlimited palettes, full version history, all export formats, shareable palettes, Figma sync, and ad removal. The Lifetime plan includes everything in Pro, future updates, and access for life. This structure suits teams that expect to maintain a reusable palette library or want a long-term design-token workflow. Smaller projects that need a simple, free color picker or teams seeking a broader design-system platform should look elsewhere.
