Color-Key (Red, Green, Blue, Overlay/VGA) Low and High Registers
(Index 30–37 hex)
These registers are used to specify the color comparison ranges for the four direct-color data fields when
performing color-key switching. A low and a high register are provided for each of the four data fields to
facilitate the range comparison. See Section 2.3.10 for more details on their usage. All four low registers
are initialized with 01 (hex), while all four high registers are initialized with FF (hex). There are eight registers
total, two for each color. The register formats for both low and high registers are shown below.
