DESCRIPTION

The setcolor utility allows the user to set various parameters on a color display, including foreground and background colors, overscan and reverse video colors, bell characteristics, and hardware scrolling.  A range of 16 colors can be used for the foreground color; a range of 8 colors can be used for the background color.  Invoking setcolor with no arguments produces a usage message and displays the 16 available colors. 

The available colors that can be specified to setcolor are:

blue magenta brown black
lblue lmagenta yellow grey
cyan white green red
lcyan lwhite lgreen lred
