HP L 5 manual Byte 0 Color Space, Byte Value Color Space

The bytes are ordered as follows and are unsigned bytes:

Byte	15 (MSB)	8	7	0 (LSB)	Byte
0	Color space		Pixel encoding mode		1
2	Bits/index		Bits/primary #1		3
4	Bits/primary #2		Bits/primary #3		5

Invalid configurations of the CID command are ignored and the data discarded. A minus or a plus sign in the value field (-6 or 6) is ignored

The data fields in the command, bytes zero to five, must contain byte-aligned binary data, not ASCII data.

Byte 0 (Color Space)

This byte specifies the color space. The range of values is 0 through 2. All other values are ignored.

Byte Value Color Space

0Device Dependent RGB (default)

1Device Dependent CMY

2Standard RGB (sRGB)

Color space 2, sRGB, was the designation for Colorimetric RGB in the Color LaserJet and Color LaserJet 5 printers. The value 2 is used to represent sRGB since it is analogous to a standardized Colorimetric RGB and the intent of the two color spaces is the same.
