8 bits = 256 colours

15 bits = 32,768 colours

16 bits = 65,536 colours

24 bits = 16.8 million colours

32 bits - same as 24 bits

 

but the extra 8 bits can be used for other things, and fits perfectly with a 32 bit PCI/VLB/EISA bus.

Additional modes are at the discretion of the manufacturer, as the VESA 2.0 document only defines modes up to 0x31F. You may need to do some fiddling around to find these extra modes.
