The Lab color space, on the other hand, is designed to be perceptually uniform. It separates lightness (L*) from color information (a* and b*), making it ideal for precise color manipulation and comparison. By converting images from RGB to Lab, we can measure color differences using Delta E (ΔE), ensuring consistent and accurate color reproduction in digital imaging workflows. Delta E quantifies the difference between two colors, allowing for objective assessment of color accuracy.
