Manually, any of the first 8 colors for text can be chosen by typing CTRL-0 thru CTRL-7 on the main keyboard. Any of the first 8 colors for background can be chosen by typing CTRL-0 thru CTRL-7 on the auxilliary keypad. The second set of 8 colors are not accessible this way. 2. The program "conf" (AKA config) can be used as follows: conf char=,back= where the color codes include all 0-15 for each. 3. Any CP/M program can change screen or text colors by outputting to the console the sequence where the color select byte uses the low bits for the color code and higher bits to specify background or character color. This, in effect, can be used by a program to display text in assorted colors on the screen. The exact interpretation of the color-select- byte is given in the CP/M section of the guide that comes with the 128. Hint: try yellow on black or green on black, perennial favorites. 80 columns on a TV set (unless it's an XBR) is going to be real squinty at best, but more contrast will definitely help.
