Had to choose between a custom color order or my last chunk of cobalt blue

A client wanted a deep purple vase but I was down to my final 200 grams of cobalt frit. I could either mix a new batch with cheaper amethyst powder or use the good stuff. I went with the cobalt, thinking it would give a richer tone. The piece came out almost black under studio lights, and the client asked if it was supposed to be a 'midnight' vase. I spent 45 minutes explaining color saturation in different light. Anyone have a reliable purple recipe that doesn't eat up your premium blues?
