RGB to HEX
Pack channels into one token
RGB values are explicit for computation; HEX is compact for CSS variables, Tailwind configs, and design token files. This conversion turns three decimal channels into a single #RRGGBB string without changing color intent.
Input guardrails
Each channel should be 0-255. Out-of-range values are usually clamped upstream, which can hide math mistakes in scripts. Double-check with HEX to RGB after copy-paste.
