# Hex Guess

> A browser game where you guess a color's hex code from sight.

Hex Guess is a game mode within Color Memory Game that displays a color swatch and challenges you to type its six-digit hex code. Guesses are evaluated using CIEDE2000 color difference rather than pure digit matching, awarding points based on how visually close your shade is to the target. It serves as a lighthearted training tool for designers and developers looking to sharpen their RGB and hex code intuition.
