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.
