Getting a strong red in CP has been discussed here in other threads and seems to be pretty elusive. Some of the mineral oxides (Burgundy or brick red) can give you a decent red but it's not a true, bright red. If you use micas, it seems like you have to use a LOT. SOmeone told me that to get a really bright sparkling red, they used something like a teaspoon for 3-4 ounces of soap, if I recall correctly. I've done a couple soaps using a couple different TKB red micas and I've found it does take an awful lot, and sometimes I still end up with it too light and pinky. I'll be eager to heard what other people have found.
