Welcome to the Cake Decorators Q&A

i have been making cakes for 35 years and just recently I have had several cakes change colour. I have started with a baby blue fondant but by next day it has changed to a mint green, I have also had pinks and reds turn shades of peach, why is this?

Hello missmopsy

This has happened sometime ago to me and to several members too. There’s a discussion here:

Hope it solves your mystery!
