Copy & run this program from SHARK.EXE. This is a SHARK program,not an html page! In your Shark system, remove the html <pre> & </pre> formatting tags, and save this file as "COLORS.PRG" or "colors.prg". It shows the usable color range of about 300 color combinations available on your monitor. It's most unlikely that you will enjoy working with hundreds of colors, instead choosing to use 3 or 4 favorites.
At the Shark prompt, after saving the file, type "do colors" or "chain colors" to run.
