The ColorSpace entry specifies how the image sample values are interpreted as colors. The number of components per sample must match the color space. For example, a DeviceRGB image requires three components per sample.

This entry must be absent for image masks. It may be absent for JPX-encoded images that carry their own embedded color space, in which case the color space is taken from the JPX data.
