Random Color Generator: For Brainstorming and Mockups
Sometimes you just need a color — a placeholder, a starting point, or inspiration to break a design block. This generator gives you random hues with optional constraints (specific lightness, saturation, hue range).
True random colors often look ugly because human aesthetics favor specific saturation/lightness ranges. A 'good' random palette uses bounded randomness: pick hue freely but constrain lightness to 30–70% and saturation to 40–80% for pleasing results.
When random colors are useful
- •Quick mockup placeholders before final colors are chosen
- •Brainstorming when stuck — random can spark unexpected directions
- •Generating distinct colors for a chart with many categories
- •Testing how a layout reads across different color schemes
Extended FAQ
How do I generate accessible random colors?
Constrain lightness — generate against your background and check WCAG contrast on each random pick. Reject below 4.5:1 for body text.
Are my generated colors stored?
No — runs entirely in your browser.
