When using _setbkcolor() in a graphics mode, you should use the
predefined color constants found in graph.h. Examples of these
constants are _BLUE, _GREEN, _RED, etc. When using _setbkcolor() in a
text mode, you should use values from 0L to 15L. These two systems of
specifying colors are not interchangeable. For instance, if you use
_setbkcolor(_BLUE) under a text mode, you will not get a blue
background.

Compiler Run-Time Library Reference" manual or query the online help
