I use my imagination each batch.. I don't follow a straight color chart or keep the amount of color in my notes.. I would google and get some ideas and see what the ct'ers have to say and then Have some fun with it!
Those aren't hard questions at all.. I follow basically the same receipe as Eugenia, I tweek it a bit until I am happy with it usually it is 1 tsp Vybar and 2 Tbs. stearic acid per lb
