CIE xyY

Derived from XYZ, x and y are chromaticity values while Y is the tristimulous value of a color.

When converting to most color types, you must supply color space and standard illuminant reference white. See available Color Spaces and Stardard Illuminants.

Color.from('xyy', [x, y, Y])

Conversion to​

.to('xyy',{
  colorSpace: string,    // optional, defaults to 'srgb' -- ignored if converting from xyz
  referenceWhite: string // optional, defaults to 'd65'
})

Get methods​

.getX(): number
.getY(): number
.getYY(): number // note the double-y for the tristimulous Y
