 about me 

screen mode
The "opposite" to multiply mode. Both parameters are inverted, multiplied by each other, the result is inverted again. This returns a brighter result than both input parameters in most cases (except one of them equals 0). Completely black layers do not change the background at all (and vice versa) - completely white layers give a white result. The average of multiply and screen mode is exactly the average mode.

f(a,b) = 1 - (1-a) * (1-b)

This mode is commutative (base and blend color can be swapped).
