Actually, both, a) and b) were named "palette" with the BGI interface. The old
EGA cards had 16 colors from a fixed palette of 64, while the newer VGA cards
had a palette of 256 from a total 262144 (2^6^3 = 2^18). The palette of the
old EGA card would be comparable to that of the C64 (in 160x200x4 mode).
