That happens with purple anything....fondant or buttercream. When I need bright colors like that I order mine already made...Satin Ice has wonderful colors and so does Fondarific. I think the sun also changes the color.

I read on here a while back to put baking soda in your fondant as your making it (I use MMF) to prevent the purple turning blue and I tried it a few months ago and it worked! I actually still have a small piece left over and it's still purple. It actually got a little darker over time but I'll take that over turning blue!

Interesting. Can you tell me how much baking soda per pound of fondant? (Or whatever ratio you use -- I can do the math.) icon_smile.gif

What shade are you trying to achieve and what coloring are using? I've never done a dark purple, but I have done lighter purple (pastel) many times and never has it turned blue on me. I just use regular old wilton gel food coloring to color my fondant. Let us know what type of fondant, gum paste and food coloring you're using...

I had the same problem a while back and posted the question. Read the thread... it appears it's a common problem. And with pinks and reds also. The baking soda/fondant proportions are in here, too.

Thanks! I'll try that next time. 1 tsp per pound of fondant.
Too bad it doesn't work like that on buttercreme. icon_smile.gif

I had to make purple roses for a wedding cake and the ones I made with gum paste turned blue too! So then I tried them with just fondant and they stayed purple no problem. I used Americolor gel a combination of regal purple and electric purple for the color. It does take a lot and made the fondant soft so I just let it sit out for a short time while I was making the roses and that worked great!

Thanks for all the tips. I was using MMF and wilton violet paste color. I will try the baking soda trick and see if that helps. FOr this cake, I just went and got a pruplespray and sprayed it. It turned out pretty well.
Thanks again!

My Wilton instructor said to mix in a tad of pink with the purple to keep it from fading. Never tried it myself though.

How much baking soda would you add? Do you just need it through dry?

I added 1 tsp to the melted marshmallows (16oz bag of marshmallows) before I added the powdered sugar. I made a purple "40" out of gumpaste and kneaded it into the gumpaste and my purple didn't fade but then it wasn't exposed to light for very long so I'm not sure if worked or not with that??

I'm wondering how long I've got until it actually fades?
I need to colour fondant for a wedding cake so I guess a cake that important I won't be able to gamble with!

Before I knew about the whole fading deal, I had left purple fondant roses on a tray sitting in front of my kitchen window. It's pretty bright there and the fading took place over the course of a 2-3 hour time frame.

I've never tried these myself, but this problem pops up all the time in here. I have seen people advise to use milk instead of water, to add some pink as it's the red that fades, so when it fades the pink is meant to allow for that. Keep it out of sunlight, or any bright light. And someone else suggested that you can try Crystal Colors, which are powdered food dusts/food coloring. Apparently the colors are really good and they don't fade.

Sunlight and florescent lights will fade fast.

Crystal Colors powder colors can be mixed into fondant, gumpaste, buttercream... and their purple doesn;t fade. I experimented with it this summer.

Did you mix to a paste a bit first?

I didn't. I just mixed the powder in with the fondant.

I'm going to try this. I need it for colouring fondant, so it sounds like ChefMaster is liquid (Am I correct?) And that Crystal Colours would be better to work with.. wish me luck! (And correct me if I'm wrong about Chefmaster!)
