Palette Mixer & Randomizer

How to use the Palette Mixer & Randomizer

1. Pick a size and mode. Choose 4, 8, 16 or 32 colors, then a generation mode — Harmonious for balanced hue theory, Monochrome for one-hue ramps, Gradient ramp to blend two endpoints, or Pastel and Dark / Moody for instant mood.
2. Roll the dice. Hit 🎲 Randomize to generate a fresh palette. Keep rolling until something clicks.
3. Lock what you love. Click the lock on any swatch and it survives the next roll — re-randomize only replaces the unlocked colors, just like Coolors.
4. Fine-tune. Use a swatch's color box to nudge any color live, or click the hex to copy it straight to your clipboard.
5. Snap to a preset or a favorite. Jump to Game Boy, 1-bit, NES-like or PICO-8-like sets, or load one of the featured palettes.
6. Export. Copy the hex list, download a GIMP .GPL file, a plain .txt hex list, a JSON array, or a PNG strip of the swatches.

Mixing palettes that actually work

A good pixel-art palette is more than pretty colors — it's a set of relationships. The Harmonious mode picks a base hue and derives analogous, complementary and triadic partners, then walks lightness and saturation up a gentle ramp so you get built-in shadows and highlights rather than a flat rainbow. That ramp is what makes a color palette generator useful for sprites: you want dark-to-light steps you can shade with. For tight retro constraints, snap to the four-green Game Boy set or a strict 1-bit pair and let shape do the work. When you land on something you like, lock the anchor colors and randomize around them to explore variations without losing the parts that already work. Every palette here exports cleanly to Aseprite, GIMP and Krita via the .GPL file or a plain hex list, so you can move from randomizer to canvas in one click. Nothing you generate leaves your browser.
