Close, but I think I'm suggesting something a little more sophisticated. It's more like it would _skip_ `colorToScalar` and instead pass more parameters into `applyColormap` (or `applyTransferFunction`). So I guess...

Yeah that's fair enough - sorry for the noise in that case, I just got excited because it seemed related! What I described might cover the behavior from this PR,...

In the meantime I'll add a couple comments on this PR :). Note `colorToScalar` is doing the same work as `colorToVal`. I prefer the name `colorToScalar` so I suggest you...
