Hello, I made mmf and I also purchase the Wilton violet color to dye my fondant , I made some loops because I am going to make a loopy bow so I left them 2 days to dry and the color fade it looks like almost white or light grey. I am wondering if this ever happen to you before and what can I do so this won't happen again.
thanks

Purple does fade badly. Americolor purple is no better. You could try using powder colours, I think they're a little better.

Whenever I make anything purple that needs drying time I put it in an open container in a dark cupboard to dry until I need it.

Thanks coral for your reply

Yes, it can be normal. Technically, its not the purple that is fading but its the red.

Red + Blue (2 primary colors) = purple.

when the red fades, it leaves blue, or sometimes will fade to gray or white-ish.

Here's the history lesson on why this happens and it goes back to the 1970s ..... http://cakecentral.com/cake-decorating-ftopict-653200-red.html+dye

indydebi thank you so much for the information it really helps, but I have another question I have seen bows that are ready made and they sell them in the internet they are super red, black, and purples how do they keep this colors? if i purchase purple, red or black ready made fondant this will keep the color for days?

I have mentioned this before, if you add 1 tsp of baking soda to 1 pound of fondant or gumpaste it will slow down the colour change in purple and pink.
I have some dark pink and purple flowers that are a year old and they have only faded a bit.

If you add just a little pink fondant to your purple fondant....maybe a marble size pink to a baseball size purple (not an exact science)...it helps.

thanks dsilvest and mommyto4 for the tips I will try that
