Color Hex
Taken from the Delphi 5 Help File:
If you specify a
Color as a specific 4-byte hexadecimal number instead of using
the Color constants, the low three bytes
represent RGB color intensities for blue, green, and red,
respectively. The value $00FF0000 represents full-intensity, pure
blue, $0000FF00 is pure green, and $000000FF is pure red. $00000000
is black and $00FFFFFF is white.
If the highest-order byte is zero ($00), the color obtained is
the closest matching color in the system palette. If the highest-order
byte is one ($01), the color obtained is the closest matching
color in the currently realized palette. If the highest-order
byte is two ($02), the value is matched with the nearest color in
the logical palette of the current device context.
