Default Color Spaces
Colors that are specified in a device color space (DeviceGray, DeviceRGB, or
DeviceCMYK) are device-dependent. By setting default color spaces (PDF 1.1), a
PDF document can request that such colors be systematically transformed
(remapped) into device-independent CIE-based color spaces. This capability can
be useful in a variety of circumstances:
• A document originally intended for one output device is redirected to a differ-
ent device.
• A document is intended to be compatible with applications designed for earlier
versions of PDF and thus cannot specify CIE-based colors directly.
• Color corrections or rendering intents need to be applied to device colors (see
“Rendering Intents” on page 260).
A color space is selected for painting each graphics object. This is either the cur-
rent color space parameter in the graphics state or a color space given as an entry
in an image XObject, inline image, or shading dictionary. Regardless of how the
color space is specified, it may be subject to remapping as described below.
