Color Palette Generator — schemes for any project

1. What does this tool do

This free color palette generator builds coordinated color sets for slides, UI design, painting, or writing. You choose how many colors you need (2–16) and a mode: random, gradient between two colors, monochromatic variants (shades, tints, tones), evenly spaced colorful hues, complementary, analogous, triadic, or tetradic schemes. Copy HEX codes instantly. All processing runs in your browser.

2. How to use it

1. Set Number of colors (2–16).
2. Pick a mode and adjust options (e.g. start/end colors for gradient, base color for schemes).
3. Click Generate palette (or Regenerate in Random mode).
4. Copy individual HEX values or copy all as lines or comma-separated text.
5. Use Color Picker to convert a swatch to RGB, HSL, or other formats.

3. How it works

Palettes are built in HSL (hue, saturation, lightness) and converted to HEX. Gradients interpolate smoothly between two colors. Complementary, triadic, and tetradic modes place hues at fixed angles on the hue wheel; if you request more colors than those anchor hues, additional swatches reuse the same hues with progressively darker lightness so the palette stays on-theme.

4. Use cases & examples

• PowerPoint / Keynote — A 5-color gradient or complementary pair for titles and accents.
• Web/UI — Triadic or analogous sets for primary, secondary, and accent roles.
• Art — Random or colorful modes for unexpected but harmonious references.
• Writing — Quick mood palettes for scenes or characters.

5. Limitations & known constraints

• Output is HEX/sRGB; print or wide-gamut workflows may need separate profiles.
• Random mode avoids duplicate HEX values but cannot guarantee perceptual spacing.
• Color Picker link opens the picker tool; paste HEX there if you need other formats.
