PaletteOS offers a web app to generate, manage, and distribute color systems across design and engineering teams. Investors include DesignSeed Partners and a few brand-led angel investors; proceeds will hire engineering and design operations staff and expand integrations with toolchains.

Key features include perceptual color interpolation, WCAG-based accessibility testing across UI states, and platform-specific token exports (CSS variables, SwiftUI, Android XML). PaletteOS also provides theming primitives for dynamic brand adjustments like seasonal palettes.

Pilot customers—mainly consumer brands and e-commerce companies—said PaletteOS accelerated brand updates and reduced accessibility regressions. The company plans a CLI for CI enforcement and a SaaS enterprise tier with audit logs and SSO support next quarter.
