# deltaE76

public final Double deltaE76(@Size(value = 3) DoubleArray lab1, @Size(value = 3) DoubleArray lab2)

Takes two CIELAB values and calculates color difference (dE) using CIE1976 formula. NOTE: both CIELAB values must share the same reference white. If they do not: convert to XYZ, adapt, convert back to CIELAB before calculating dE

#### Return

delta E (1976) value

#### Parameters

lab1

First CIELAB value (element order L, a, b)

lab2

Second CIELAB value (element order L, a, b)
