When to use it
Stuck with a color as separate R, G, B values from a JavaScript canvas API and need it in CSS? Enter 230, 57, 70 and you get #e63946 right away, ready to drop into a stylesheet or design token. It also saves you the mental math whenever a design tool hands you RGB but your codebase expects HEX.
