Ok, so the reason it's not working the way you expect is due to the bpp. Vanilla LRR runs in 16bpp colour space, your level picker image is 24bpp. When LRR loads the levelpicker image it converts from 24 to 16bpp. 16bit supports 65,536 colours. 24bit supports 16,777,216 colours. As you would expect, this conversion results in near colours being merged. So you can expect R1 G1 B1 to become R0 G0 B0 and this is actually the case in some LRR bmps where the transparent colour is not true black, such as the radar panel.
