Hi Anthony,

The RGB components of bg_data are brightness values not colour values.
Therefore the colour is specified in the actual tile image.
RGB of 0x80 will give you normal brightness, RGB of 0 will give you black
and an RGB of 255 will give you white.
I haven't used BG functions yet but I think this is correct.

Rad.
