freepalettegen.app generates beautiful 5-color palettes using proven color theory. Pick a base color and choose from five harmony modes — complementary, analogous, triadic, tetradic, or monochromatic — and get an instant palette with hex codes ready to copy. Upload any image to extract its dominant colors. No signup, no ads, everything runs in your browser.
freepalettegen.app converts your base color to HSL (hue, saturation, lightness) and applies mathematical color harmony rules. Complementary mode shifts hue by 180 degrees. Analogous mode creates hues spaced 30 degrees apart. Triadic mode spaces three hues evenly at 120-degree intervals. Tetradic (square) mode places four hues at 90-degree intervals. Monochromatic mode varies lightness and saturation while keeping the same hue. Each palette contains five colors ready to copy as hex codes.
Yes. Upload any photo, screenshot, or design and freepalettegen.app samples the pixels using the Canvas API to find the most dominant colors. The algorithm quantizes the image into color buckets and returns the top colors as a palette. Your image never leaves your browser — extraction is 100% client-side.
Complementary palettes create high contrast — ideal for call-to-action buttons and hero sections. Analogous palettes feel harmonious and natural — great for backgrounds and UI themes. Triadic palettes are vibrant and balanced — suited for data visualization and infographics. Tetradic palettes offer the most variety — useful for complex interfaces with many components. Monochromatic palettes look clean and professional — perfect for minimalist designs and brand systems. freepalettegen.app lets you switch between all five with one click.
