Note the following regarding 1-bit mode:

"The bitmap is monochrome, and the bmiColors member of BITMAPINFO 
contains two entries. Each bit in the bitmap array represents a pixel. 
If the bit is clear, the pixel is displayed with the color of the first 
entry in the bmiColors table; if the bit is set, the pixel has the color 
of the second entry in the table."

Monochrome doesn't mean black & white here, merely bi-level, as for PNG, 
TIFF and QuickTime.
