The only other color is BLUE. If everything is shades of blue you may
have a monitor, cable or connector failure(check connections and or
attach to another. If you are only missing Pure red and Pure Green then
you need toy check the video card settings and the monitor color
adjustment. In which case please refer to the manuals for your hardware
for adjustment instructions.
