The BackColor property returns the current background color
for the control. Setting the property changes the color to the
specified value. This value does not affect page transparency and it
is important to note that this setting does not override the
background defined by the currently loaded page. If the page specifies
its own background color or image, that content will take precedence
and may obscure the configured color. For example, setting the
background to white will not force web pages to appear white unless
the page itself has transparent regions.
Colors are RGB (Red Green Blue) values which range from 0 to
16,777,215 (&HFFFFFF). The high byte of a number in this range
equals 0; the lower 3 bytes, from least to most significant byte,
determine the amount of red, green, and blue, respectively. The red,
green, and blue components are each represented by a number between 0
and 255 (&HFF). If the high byte isn't 0, the control uses the
system colors, as defined in the user's Control Panel settings.
The following table lists the standard system color values and the
Control panel settings that they correspond to:
