can someone explain why the resulting blends are not black throughout the range of the input sliders? and why, when their inputs are ran through a tonecurve that does nothing, they turn black.

thanks:)

My best guess is that the precision of the internal calculations differ. Your last question is easy to answer - you look at the difference btwn the same source (nonsense) - of course you'll see black smile:-p
