Your problem, then, is how to display the colour formed when both red and
yellow are at 255. This would be give-or-take 510,255,0 RGB and is too
bright to represent on your monitor.
A good starting point would be to halve everything, so 100% R = 128,0,0 and
100% Y = 128,128,0 - and turn up the monitor brightness.
You might need to think about gamma correction though.
