ColorSpace

is an option for Image and related functions that specifies the color space to which color values refer.

Details

Color spaces, also known as color models, provide numerical models to represent colors. Some models such as RGB are designed to better represent colors on devices, and some like CIELAB are more suitable for perceptual color comparison.
Color spaces supported by Image and Image3D include:

	"Grayscale"	gray level (GrayLevel)
	"RGB"	red, green, blue (RGBColor)
	"CMYK"	cyan, magenta, yellow, black (CMYKColor)
	"HSB"	hue, saturation, brightness (Hue)
	"XYZ"	CIE XYZ (XYZColor)
	"LAB"	CIE (LABColor)
	"LCH"	CIE
