Why isn't there deindexing for TAM_I_TargetRedPercent, TAM_I_TargetGreenPercent, TAM_I_TargetBluePercent variables?
I think you could expand this sightly, so that you could have transitioning colour, besides the transparency. You could also add a small description here just for the people to get the gist of it.
At the top of my head I can't think that many scenarios that this would be usable, but it's still useful for certain effects.
