Simple Color Palettes

The Simple Color command (?*r#U) provides a quick way to select colors from a fixed, non-programmable palette.

The Simple Color command overwrites the current palette with one of the fixed palettes below. When the Simple Color command is in effect, the PCL and HP-GL/2 commands that modify a palette entry (NP, CR, PC, ?*v#A, ?*v#B, ?*v#C, ?*v*I, ?*t*I) are locked out. A popped simple color palette cannot be modified and the pixel encoding mode reverts to “index by plane”. Only the IN or the CID?( *v#W) commands can create a modifiable palette.

As shown below, a value field of 1 (?*r1U) creates a black and white palette. A value of 3 creates an 8-pen palette in Device RGB color space. A value of –3 creates an 8-pen palette in Device CMY color space. All of these Simple Color palettes are fixed and non-programmable.

5	Magenta
