However, .bmp is limited to a 16-color palette. This may or may not be problematic, depending on whether color is involved in the first place and depending on what colors are used in the interface.

Dick is usually such a reliable source of information, I'll write that
one off to not enough coffee. :-)
A 16-color palette is 4-bit color depth. The term "palette" is
appropriate only for 4- or 8-bit (AKA indexed color) images, which use a
table, or palette, to define the 16 or 256 colors (24-bit colors) that
they contain, and pointers to the table entries to specify the pixel
colors.
I have lots of 24-bit BMPs (16 *million* colors). I don't know if the
BMP format supports 30-bit or 36-bit color -- probably not, but who
cares? ;-)

I sit corrected. It has been a long time since I've used BMPs, and that was only through the MS Paint application, which supported only 16 colors at one time (maybe Windows 3.1? As I said, it has been a long time).
