Additive Transparency


The flames on this burning bed are using additive transparency to keep the colors "hot."

See additive color model.

Subtractive Transparency


The x-rays on this light-table use subtractive transparency to make things under them darker, the way real x-rays do. The subtractive method isn't used all that often, so if you need it you should ask your programmer(s) if they can add it as a specific feature of the engine.
