Random Color Generator
Generate random HEX colors with crypto randomness.
Random Color Generator creates cryptographically strong random HEX colors—optionally pastel—for moodboards, placeholders, and experiments.
How it works
Set count|mode (vivid or pastel) and generate. Bytes come from crypto.getRandomValues and map into RGB HEX values.
Benefits

- Treating random HEX as accessible by default
Privacy
