Sure, you can see through them, like a veil, but it's not the same as
being truly transparent. I like being able to put yellow over black
(as in adding an extra layer of yellow as a fourth layer over a
tricolor) without there being any evidence of the yellow as a separate
layer over the black. PY110 is the only yellow I know that can do that.

One of the things I plan to do this week is print a bunch of different
yellows as the last layer on a tricolor, to show the difference.

My point earlier was that each pigment has its own unique character,
that's what's so cool about pigments: no two are the same, and they
aren't interchangeable.
