colour depth

(bpp) The number of bits of information
stored per pixel of an image or displayed by a {graphics
adapter}. The more bits there are, the more colours can be
represented, but the more memory is required to store or
display the image.

A colour can be described by the intensities of red, green and
blue (RGB) components. Allowing 8 bits (1 byte) per
component (24 bits per pixel) gives 256 levels for each
component and over 16 million different colours - more than
the human eye can distinguish. Microsoft Windows [and
others?] calls this truecolour. An image of 1024x768 with
24 bpp requires over 2 MB of memory.

"High colour" uses 16 bpp (or 15 bpp), 5 bits for blue, 5 bits
for red and 6 bits for green. This reduced colour precision
gives a slight loss of image quality at a 1/3 saving on
memory.

Standard VGA uses a palette of 16 colours (4 bpp), each
colour in the palette is 24 bit. Standard SVGA uses a
palette of 256 colours (8 bpp).

Some graphics hardware and software support 32-bit colour
depths, including an 8-bit "alpha channel" for transparency
effects.
