To confuse matters even more, some brands of Ultramarine blue are listed as reddish ultramarine, greenish ultramarine and so on. It's too bad there isn't some sort of standard but there isn't.
While teaching a workshop, I was using Liquitex Indian Yellow which is a transparent. A student had a tube of Indian Yellow from Cheap Joes and that brand was completely opaque and will of course give a totally different result.
Just beware of what you are buying and what the paint manufacturers are selling. It can get confusing.
