Just wondering if anyone has ever had this happen? I frosted 2 cakes in VERY bright colors, came back a few hours later and they were no longer bright, not even close. One was very bright pink and when I came back it was very light pink. My other one was bright purple and when I cam back it was half blue, and half lighter purple. What happened? I did nothing different, this has never happened!

Hate when that happens...from my experiences....I have learned to let the colours bloom for a few hours before I ice the cake...they change as they sit...overnight is even better...maybe you can paint over the exisiting color...

I knew just be reading the subject line that it involved red fading.

Here's your history lesson that I've shared a number of times (since most of you aren't as old as I am and were around back then! icon_lol.gif ).

In the late 70's, Red Dye #2 was removed from the market. Inconclusive testing determined that if you ate something like 500 lbs of it a day, you MIGHT get cancer, so they pulled it. There was no substitute that was as stable. Bright lights, sunlight will cause the reds of today to fade.

Purple = blue + red. Red fades, leaving only the blue.
Orange = Red + yellow. Red fades, leaving only the yellow.
Red fades to pink .... pink fades to light pink or even white.

Many CC'ers have said using milk instead of water in your icing helps stablize the color. Brands of color makes a difference. I use Cake Craft brand colors and rarely, if ever, have a fading issue.

BUt what you experienced is actually pretty normal.

and adding to IndyDebi's history lesson: physics/chemistry/lighting lesson --

specifically it is the UV in light that causes the fading (yep UV is a bleach! -- one reason why whites hung outside in sun look so much white and brighter -- and why it can be used to disinfect things and why it can disrupt cell structure to cause cancer!)

UV sources: sunlight -- so keep away from windows -- doesn't even have to be direct light!

florescent lights (at their heart they are a very powerful UV source -- think tanning beds!) -- so keep those off too! (tho' that could be difficult -- hard to see in the dark.

best protection -- ice it -- box it immediately so the light can't get to it.

(some one needs to invent cake sun screen!)

I've only had fading problems with Wilton Pink. I use Wilton Rose for all my pink icings now and never have any problems.
