| Short Description | ShortDesc::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, LoRes and 1-bit ("text mode") tilemap. Sprites use {{#ask: TBRegisterNumber::$4B }} ($4B) for transparency, 4-bit Tilemap uses {{#ask: TBRegisterNumber::$4C }} ($4C).
