For some reason pure green uses the green and clear pixels whereas pure red and blue are one pixel of the colour and up to three pixels of black - I assume light red would have the R and W pixels white and the G and B pixels black. Lots of fun to be had - I haven't had much time since getting the jetBook Color but I'll try and add a few more investigations as time permits.

Another interesting thing to notice is that even the coloured letters aren't actually too blocky in outline - they still use the 1200x1600 sub-pixels and aren't made out of solid 2x2 square "Lego bricks".
