What's the correct way of using drawPixel with monochrome panels?

[DoomHammer]

I'm trying to draw pixels on a monochrome board (red). I tried setting the color to either RED or WHITE but no luck. Is there something I'm missing?

There are only two "colors" that monochrome panels supported - 1 (led on) and 0 (led off).
See the monochrome example.
