So I purchased a mixed bunch of series 4 oil paints (because it was a lot cheaper that way), but I'm unfamiliar with one of the colors: Indanthrene Blue (PB60).
So far I've been able to gather it's a semi-opaque blue/violet, but it doesn't appear to be an especially popular color since I haven't found a lot of info about it's uses online. So far the majority of info I find about it is regarding it as watercolor paint: http://www.handprint.com/HP/WCL/waterb.html.
So my question is: as a beginner, should I stash this one in a drawer or use it despite not really being able to find a lot of good advice on what to use it for?
