  • ColorBox

    FreeProprietaryWeb

    ColorBox is free and gives curve-based control of each channel with contrast ratios per step, exporting to Tailwind CSS, OKLCH and Swift, though its controls take some learning.

  • Atmos

    A web-based color palette generator for UI designers, with shade scales and accessibility checks.

    FreemiumProprietaryWeb

    Atmos is also freemium and builds uniform shade scales with semantic status colors and accessibility checks, without being tied to Tailwind CSS naming.

  • Huetone

    Huetone is free and open source, building accessible LCH-based scales across hues, and assumes some familiarity with color spaces instead of Tailwind conventions.

  • Accessible Palette

    FreeProprietaryWeb

    Accessible Palette is free and focuses on consistent lightness and WCAG contrast across hues, but does not describe Tailwind export or UI previews.
