You can use colorimage, but it is a very inflexible way to define
images. The level 2 image operator with dictionary is much more
flexible. For example, you would need to use this if you wanted an
Indexed color space.

The colorimage operator just works with two color spaces, DeviceRGB
(if number of components is 3), and DeviceCMYK (if number of
components is 4).

Note that "number of components" is not at all the same as "bits per
component". With the image dictionary form there is no "number of
components" setting because it uses the current color space, and
therefore knows how many components to look for in the data.

If you feel you can do a better conversion from RGB to CMYK than
PostScript, then you can do this before using image or colorimage.
Otherwise, if you currently have no idea how to do the conversion then
you might as well let PostScript convert.
