Palettro

Palettro generates harmonious color palettes the moment you move a slider — no account, no internet, no friction. Pick any seed color with the HSB controls and choose a harmony mode: Complementary, Analogous, or (with Pro) Triadic, Split-Complementary, and Monochromatic. Tap any swatch to copy its HEX, RGB, or HSL value instantly. Designers use Palettro to draft a color scheme before opening Figma. Developers copy Swift or CSS color variables directly from the export sheet. It's the fastest way to go from an idea to a working palette on your phone. — WHAT MAKES PALETTRO DIFFERENT — • Five harmony modes — Complementary, Analogous, Triadic, Split-Complementary, and Monochromatic, all built on precise HSB controls. • Instant slider-driven generation — every palette updates live as you move the seed color slider. • One-tap value copy — copy HEX, RGB, or HSL instantly from any swatch. • Developer-ready export — export as CSS variables, Swift Color, or JSON. • Built for the whole workflow — draft a scheme before opening Figma, then copy code straight from the export sheet. — PRICING — Palettro's free tier includes Complementary and Analogous modes, one-tap HEX/RGB/HSL copy, and up to 3 saved palettes. Palettro Pro is a one-time unlock that adds Triadic, Split-Complementary, and Monochromatic modes, unlimited saved palettes, export as a HEX list, CSS variables, Swift Color, or JSON, and palette extraction from any photo.
