Feature request: isWarmColor, isCoolColor, isDarker, isLighter, isHarmonious

[ex-tag]

Warm colors have more red, and cool colors have more blue.
Please add isWarmColor() and isCoolColor() methods.

To check RGB color, code might look like...

red = 0
blue = 0

if (red > blue) {
  isWarmColor = true
  isCoolColor = false
}
else if (red < blue) {
  isWarmColor = false
  isCoolColor = true
}
else {
  isWarmColor = false
  isCoolColor = false
}

[ex-tag]

isWarm - checks if color is Warm color
isCool - checks if color is Cool color
isWarmer - checks if one color is warmer than another color
isCooler - checks if one color is cooler than another color
isLighter - checks if a color is lighter than another color

Isn't there any warmer/cooler manipulators?
