The BitBLT Background Color Registers form a 16-bit register that specifies the BitBLT
background color for Color Expansion or the key color for transparent blits. For 16 bpp
color depth (REG[101h] bit 0 = 1), all 16 bits are used. For 8 bpp color depth (REG[101h]
bit 0 = 0), only bits 7-0 are used.

The BitBLT Foreground Color Registers form a 16-bit register that specifies the BitBLT
foreground color for Color Expansion or the Solid Fill BitBLT. For 16 bpp color depth
(REG[101h] bit 0 = 1), all 16 bits are used. For 8 bpp color depth (REG[101h] bit 0 = 0),
only bits 7-0 are used.
