calculateCoolWarmFactor
Computes the cool-warm factor of a color.
The cool-warm factor indicates whether a color is perceived as cool or warm based on color science.
Values below 0 are considered cool.
Values above 0 are considered warm.
This method uses the Lab/LCH color space and the algorithm from Ou, Woodcock, and Wright. The range of the factor is approximately -9.66 (cool) to 8.61 (warm), assuming maximum Lab chroma.
Return
A value indicating the cool-warm factor of the color. Values below 0 are cool, and values above 0 are warm.
Parameters
color
The color to compute the cool-warm factor for.
