 about me 

hard light mode
Another combination of screen and multiply mode, depending on the blend color (the "opposite" of overlay mode - NOT the "opposite" of soft light mode! - in fact the names of overlay mode and hard light mode should be swapped to be more logical).

f(a,b) =  2ab (for b < ½)
1 - 2 * (1 - a) * (1 - b) (else)

There is a separate formula for bright and for dark blend colors, so there is a discontinuance for b = ½ (diagram 1 can be sparated into two parts).
