Probably because your Windows video driver takes away some of the
colors for its own use.

The "standard VGA" Windows video driver uses only 16 colors, and they
can't be altered.  Even a "256-color" Windows video driver reserves
20 colors for its own use, and only lets application programs such as
Winfract alter the other 236.   ("True-color" Windows video drivers 
let applications programs set their colors at will.)

Winfract doesn't attempt to dither its internal colors into a scheme
that accounts for the above limitations (who knows what those
limitations will be under Windows 3.2?).   It just hands its
device-independent bitmaps over to the Windows video driver and says,
in effect, "here - display this".  The Windows video driver then
typically attempts to reduce Winfract's palette into one that matches
the available colors using a "best fit" approach that doesn't always
fit so well.  My 256-color Windows driver, for example, often 
matches the last 20 colors to a stylish solid-black <grin>.
