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.
