🎲 How Randomness Works

Numbers are generated using JavaScript's Math.random() — a fast pseudo-random generator suitable for games, sampling, and decisions.

With No Repeats enabled, a Fisher-Yates shuffle builds a pool of all possible values and draws without replacement — guaranteed zero duplicates.

🎨 Hex Color Format

Selecting Hex Color converts each number to a 6-digit #RRGGBB value — the same format used in CSS and design tools.

Use the Hex Color quick range (0–16,777,215) to generate completely random colors, or stay in 0–255 for single-byte hex values.
