BC [n1],n2[,n3,n4] n1: Bitplane to be coloured <last bitplane> n2: Red grey level (or colour code) <0> n3: Green grey level <0> n4: Blue grey level <0>If n2,n3,n4 are all specified, the graphic plane colour is set explicitly to the specified RGB colour. If n3,n4 are not specified, and n2 is between 1 and 16, then n2 represents a colour code.
n1 is the bitplane, within an unspecified image plane, which will be assigned the given colour.
Bitplanes are bit-sliced planes within an image plane, and are numbered 1 to 8. Data are entered into bitplanes with the task BBT to create an O-map, which is then loaded to an image channel on the display before applying this group of interactive bitplane commands in DCP.
The available colour codes and their RGB values are listed below:
