Is this what you see?

Hi Martin,

Yes, that matches exactly what I see. The blue tinge I was referring to only appears if I override the bit-depth clamping to 15 whilst forcing QEMU to use a 16 bit-depth framebuffer with "-g 800x600x16", i.e. HelenOS doesn't use the correct VISUAL_RGB_5_6_5_BE constant for a 16 bit-depth framebuffer as pointed out in Martin's previous email.
