I believe the word is "transmit."

To my knowledge, the math applied to get a result color is:

filtered color = (front color) * (background color) * [FILTER] + (front
color) * (1 - [FILTER])
final color = (background color) * [TRANSMIT] + (filtered color) * (1 -
[TRANSMIT])

I'm not positive about the filter stuff, but I'm pretty sure about the
transmit stuff. The math applies even when filter or transmit are outside
the range [0,1].
