Soap Colorant Questions:

Up 'til now I've colored my soaps with only clays and alkanet root.  I'm wanting to try oxides and/or micas, but I don't really know where to start.

Is there a clear advantage of one or the other in CP soap?

I'm wanting to try a blue for sure (I was looking at Brambleberry's 1982, but it's out of stock at the moment), pink, green and maybe even purple are of interest to me as well.  Does anyone have any specific suggestions?  I've noticed that some say that they don't work well in CP, which is what I'll be using them in.

Suggestions of what you've used with good results in CP soap would be GREATLY appreciated! 

Happy Soaping Everyone! :)
