Transparency color value (0xE3 after a reset).
This value is 8-bit only, so the transparency is compared only by the MSB bits of the final colour.
This only affects Layer 2, ULA, LoRes and 1-bit ("text mode") tilemap. Sprites use Sprites Transparency Index Register ($4B) for transparency, 4-bit Tilemap uses Tilemap Transparency Index Register ($4C) except in text mode.
