Byte 0 (Color Space)
Value Color Space
0 Device RGB (default)
1 Device CMY
2 Colorimetric RGB Spaces
3 CIE L*a*b*
4 Luminance-Chrominance Spaces
A color lookup table can be attached to one or more of the
color spaces anytime after a CID command. For example, a
Luminance-Chrominance space can have four lookup tables
specified, namely:
Device-Dependent space
CIE L*a*b* space
Colorimetric RGB space
Luminance-Chrominance space
A reset (?E), IN, or CID command sets each of the four
levels of color lookup tables for each primary to the unity
curve.
