About the Color Palette Generator
A color palette generator takes the guesswork out of picking colors that actually work together. Instead of staring at a color wheel trying to remember which hues are supposed to sit next to each other, you press a button and get five colors that already form a coherent set. This tool builds each palette from real color theory rules — complementary pairs, analogous runs, and split relationships — rather than picking random hex values, so what you get out is usable straight away, not just decorative.
How it works
Every time you generate a palette, the tool picks a random base hue and then rotates around the color wheel using one of several harmony rules to produce the remaining four colors. Saturation and lightness are varied slightly between swatches so the palette has visual rhythm instead of five flat, same-intensity blocks. If you find a color you like inside a palette, click the lock icon on that swatch — locked swatches stay fixed while the rest of the palette keeps regenerating, which is the fastest way to build around a color you already know you want to use, like a brand color or a photo's dominant tone.
Common use cases
- Choosing a five-color brand or website palette in minutes
- Finding accent colors that complement a fixed primary color you lock in
- Building a quick moodboard palette for a pitch deck or client presentation
- Generating color options for illustration, UI design, or data visualization work
- Exploring color theory by watching how hue relationships shift as you regenerate
Tips for best results
Lock your most important color first — usually a brand color or the dominant tone from a product photo — then keep regenerating until the remaining four feel balanced. For interfaces, aim for one dark neutral, one light neutral, and three accent colors rather than five colors of similar intensity, since that tends to read as more usable and less noisy on screen.
Frequently asked questions
Each generated palette contains five colors, which is a practical number for most branding and UI work: enough room for a primary, a secondary, an accent, and two neutrals without becoming overwhelming to apply consistently.
Yes. Click the small lock icon in the corner of any swatch before generating again. Locked swatches are skipped by the randomizer, so you can build a full palette around one anchor color step by step.
Palettes exist only in your browser session for now — nothing is uploaded to a server. Copy the hex codes you want to keep, or use the copy button under each swatch, before you close or refresh the tab.
Each swatch displays its value as a HEX code, which you can copy directly with one click. If you need RGB or HSL for the same color, paste the HEX value into the HEX/RGB/HSL Converter tool.
The generator focuses on aesthetic harmony rather than contrast ratios, so once you've picked colors you like, run your text and background combination through the Contrast Checker tool to confirm it meets WCAG AA or AAA before shipping it.
