よくある質問
What format are the colors in?
Each color shows as a hex code (#RRGGBB) and its RGB values, with a swatch you can click to copy.
Can I generate a palette instead of one color?
Yes. Set the count to generate several colors at once, shown as a row of swatches.
Are the colors truly random, or from a preset palette?
Fully random RGB values via crypto.getRandomValues — not drawn from a fixed preset list.

- Using a random color generator to break a creative rut
Staring at a blank canvas is easier when someone else picks the first color. How random RGB draws force a constraint you didn't choose, and how to pair them with drawing and photo prompts for a full creative warmup.
