PalettroInstant Color Palette Builder

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.
