QuickDraw from a complicated guessing game into a more-or-less predictable process.
ColorSync provided a standard API that could produce WYSIWYG color output if used by

QuickDraw GX goes a step farther, fully integrating ColorSync for color management.
When you create a QuickDraw GX application or printer driver, you don't need to
