I’m sure the math is complex, but at least on my system, it just looks 
like a *very* subtle ‘lighten’ effect.

And at first, I didn’t think it worked *at all*, as the thing I was 
drawing disappeared as soon as I let go of the mouse button. But after a 
bit more testing, I see that it does lighten (non-dark) areas somewhat 
and adds a (too) subtle glow effect.
