DeltaE: 0
Delta E(ΔE)
Delta E(ΔE) is a metric used to measure and compare colors. Originally developed by the International Commission on Illumination (CIE), it evaluates the difference between two colors in a multi-dimensional space to provide a quantitative value depicting color difference.
This metric is useful in many fields, such as in digital imaging, textiles, plastics, and paint manufacturing where precise color matching is required.
A smaller Delta E value implies a smaller difference between the two colors. Typically, a Delta E of less than 1 is not perceptible to the human eye. A value between 1 and 2 is considered a perceptible difference, but still very close. A value of 2 or more is where a human eye can clearly see a difference.
It's important to note that the Delta E measurement cannot specify in which way the colors differ, it only quantifies the amount of difference. There are multiple formulas to calculate Delta E, and the most common ones include CIE76, CIE94, and CIEDE2000, with each having varying levels of precision and complexity.
Examples
#FFFFFF(White) - #000000(Black) = DeltaE 100
#FFFFFF(White) - #FF0000(Red) = DeltaE 45.81
#FF0000(Red) - #0400FF(Blue) = DeltaE 52.85
