What is Delta E?

Delta E (ΔE) is a metric used to quantify the difference between two colors as perceived by the human eye. The "E" stands for "Empfindung," the German word for sensation. Delta E 2000 (ΔE2000) is the latest and most accurate version of this metric, taking into account the complexities of human color perception. It measures color difference on a scale where lower values indicate more similar colors: a ΔE of less than 1 is generally imperceptible to the human eye, while values above 10 represent noticeable differences.

Tool description

This color difference calculator measures the perceptual difference between two colors using the Delta E 2000 calculator formula, which is the industry standard for color comparison. It functions as both a color perception test and a practical measurement tool, providing numerical values that represent how different colors appear to human vision. The calculator includes a perceptibility rating that helps you understand the practical significance of the difference. Designed for designers, developers, and color professionals, this tool ensures color consistency and helps evaluate color variations with precision.
