Defining Color Spaces

Color Space Signatures

A ColorSync profile header contains a dataColorSpace field that carries the signature of the data color space in which the color values in an image using the profile are expressed. This enumeration defines the signatures for the color spaces supported by ColorSync for version 2.x profiles.

enum {
   cmXYZData   = 'XYZ ',
   cmLabData   = 'Lab ',
   cmLuvData   = 'Luv ',
   cmYxyData   = 'Yxy ',
   cmRGBData   = 'RGB ',
   cmGrayData  = 'GRAY',
   cmHSVData   = 'HSV ',
   cmHLSData   = 'HLS ',
   cmCMYKData  = 'CMYK',
   cmCMYData   = 'CMY ',
   cmMCH5Data  = 'MCH5',
   cmMCH6Data  = 'MCH6',
   cmMCH7Data  = 'MCH7',
   cmMCH8Data  = 'MCH8'
};
