Details

The GASK('COLREP', . . . ) routine returns the predefined SAS color name associated with a color index. GASK('COLREP', . . . ) searches for the current color assigned to a color index in the following order:

the color selected by the GSET('COLREP', . . . ) function.
the COLORS= graphics option. If color-index is 2, the routine returns the second color from the color list of the COLORS= graphics option.
the device's default color list found in the device entry. If color-index is 2, the routine returns the second color from the default color list.

See SAS Color Names and RGB Values in the SAS Registry for a list of SAS predefined color names.
