The Color Profile Object
A color profile describes how to match a color with the colors in a color space. QuickDraw GX provides you with access to an individual color profile object through a gxColorProfile reference:
typedef struct gxPrivateProfileRecord *gxColorProfile;In this type definition, gxColorProfile is a type-checked reference, not an actual pointer to any defined structure. The contents of the color profile object are private.Color profile objects contain color profile structures as defined by the Macintosh ColorSync Utilities. See Inside Macintosh: Advanced Color Imaging for more information.
