[Sa'ar Chasm]

I think we've got the "seethroughability" range pinned down to transparent and opaque, but I'm not sure that transparent=clear.

I've got an M.Sc. in Chemistry that says it does. Plain water is clear and colourless. Kool-Aid is clear and coloured.

What color is "water-white" supposed to be?

Colourless. There's a reason it's not used anymore.
