"This means that 24-bit color and 32-bit color actually have the same
number of colors available to them, but 32-bit color just has some added
information for transparency. So if you don't need the extra info, 24-bit
is better than 32-bit, right? Well, not exactly. It's actually kind of a
pain to deal with, because there's no data type that's 24 bits. So to
write a pixel, instead of just writing in one value, you have to write
red, green, and blue each individually. Working in 32-bit color is
probably faster on most machines, even though it requires more memory. In
fact, many video cards don't support 24-bit color at all, because having
each pixel take up three bytes is just too inconvenient."

"They that can give up essential liberty to obtain a
little temporary safety deserve neither liberty nor
safety." -- Benjamin Franklin
I would rather be exposed to the inconveniences attending too
much liberty than to those attending too small a degree of it.
-Thomas Jefferson 1743-1826)
