Technical Specification & Mathematical Principles

Integer RGB channels in the range [0, 255] are converted to base-16 strings using Math.round(val).toString(16).

To maintain structural integrity, single-character results are padded with a leading zero via padStart(2, '0') before concatenating into #RRGGBB.

Frequently Asked Questions

Each color channel in an 8-bit hex string must occupy exactly two characters (from 00 to FF). If a channel calculates to a value less than 16 (such as 9), failing to pad with a leading zero would result in an invalid 5-character hex code.
