Colorizer, Build 2 (Optimized)

24/25 fps.

EDIT: Too negative values will cause the effect to disappear (e.g. used on red channel, a too negative value will make red become "old red" again)

What do you mean by "too negative"?
Also, there's a new build that is MUCH more optimized:

I just noticed it by chance - I had something like "new red to old red" = 1 - timer * 0.001"
And after a while of red becoming less, red suddenly was fullbright again.

EDIT: Okay, I made a quick test. By "too negative" I mean "below zero". As MMF needs to be as error tolerant as possible, IMHO extensions should treat "wrong" input liberately (clamp input).

EDIT: Never mind. Fixed in Build 4.
