Byte 0 (Color Space)
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.
