Thanks Soapbuddy. It always looks gray to me right after I put it in the mold but hasn't stayed that way yet. I finally got a nice dark(er) purple yesterday. I kept adding bits of pigment until the mix looked about right. It looked sky blue right at gel but ended up a really nice purple.
Hopefully I didn't get so much pigment in that the lather is blue. Ask me how I know about that phenomenon...

I've been avoiding the FD&C colors for the moment in an effort to reduce variables and try and learn as much as I can about pigments before moving to the next process.
