The Color Difference Engine provides precise mathematical tools to measure how different two colors appear to the human eye. By translating digital Hex values into perceptually uniform color spaces, it allows for accurate comparison using industry-standard models like CIEDE2000 and modern standards like OKLAB. Use calculate_color_difference to find the distance between two specific colors, or rank_colors_by_similarity to sort a list of candidates against a target. The engine also features evaluate_proximity for threshold-based matching and get_color_components to extract lightness, chroma, and hue dimensions.
