Hi everyone, can anyone tell me why my gumpaste are loosing their color? I dyed pink gumpaste for roses but they seem to be significantly lighter this morning. I pretty aggravated. What could cause this?

Was the gumpaste still wet last night? If so, there's your reason. It's the same concept as with paint: the color of it wet will be different that the color of it dry. Maybe some airbrushing or petal dust to enhance the color might help?
