| Short Description | Sets the "transparent" colour for Layer 2, ULA and LoRes pixel data. |
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 and LoRes. Sprites use Sprites Transparency Index Register ($4B) for transparency, Tilemap uses Tilemap Transparency Index Register ($4C).
