Color and Color Spaces

Devices (displays, printers, scanners, cameras) don’t treat color the same way; each has its own range of colors that the device can produce faithfully. A color produced on one device might not be able to be produced on another device.

To work with color effectively and to understand the Quartz 2D functions for using color spaces and color, you should be familiar with the terminology discussed in Color Management Overview. That document discusses color perception, color values, device-independent and device color spaces, the color-matching problem, rendering intent, color management modules, and ColorSync.

In this chapter, you’ll learn how Quartz represents color and color spaces, and what the alpha component is. This chapter also discusses how to:

• Create color spaces

• Create and set colors

• Set rendering intent
