true color

True color is the specification of the color of a pixel on a display screen using a 24-bit value, which allows the possibility of up to 16,777,216 possible colors. Many displays today support only an 8-bit color value, allowing up to 256 possible colors.

The number of bits used to define a pixel's color shade is its bit-depth . True color is sometimes known as 24-bit color . Some new color display systems offer a 32-bit color mode. The extra byte, called the alpha channel , is used for control and special effects information.

Inaccurate information even for the last time this article was updated in 2005, by 2005 the norm for color depth displays was default a 32-bit truecolor scheme, for some one in the 'biz' of IT and general tech this is a failure on so many levels its sad really.

Wrong information. 8-bit color and 24-bit are same. 8-bit means, 8-bit per channel (Red, Green and Blue) which ends up in 8+8+8 = 24 bit.
