# deltaE00

fun deltaE00(@Size(value = 3) lab1: DoubleArray, @Size(value = 3) lab2: DoubleArray, kL: Double = DELTA_E_KL_DEFAULT, kC: Double = DELTA_E_KC_DEFAULT, kH: Double = DELTA_E_KH_DEFAULT): Double

Takes two CIELAB values and calculates color difference (dE) using CIE2000 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 (2000) value

#### Parameters

lab1

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

lab2

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

kL

Model parameter (default 1)

kC

Model parameter (default 1)

kH

Model parameter (default 1)
