I have been looking at all these wonderful Halloween cookies here and have couple questions. How do I get my icing so deep blue purple for the night sky (I only have Wilton colors available) and what is the secret to get yellow and green icing to glow?

well impretty new at all this sorry if im no help. for the dark deep purple u could use a tiny bit of the wilton black then add some purple becaue the black istn actually black anyways haha

To get dark shades in buttercream you have to make the icing at least the night before you want to use it; also start by coloring your icing a medium color (blue or purple) allowing that to 'mellow' a few hours before adding more navy blue gel &/OR some black. Don't use too much black so you keep the blue coloring.

It's about the same if using royal icing but royal dries just a shade or two *lighter* so go darker than you think you need It also doesn't take as long to develop the color as b'c does.

Sorry, can't help w/the glowing colors.

Have you pm'd the member and asked what they used for the glowing cookies? I havent seen any like that. Have you tried the Americolor Electric colors? They have Orange, Yellow, Green, Blue, Pink and Purple.

Thank you for your suggestions. I did not even think of pm, but I will do it now. And I have more then a month to practice. It seems that most people here prefer Americolor, I will go to their website and buy some.

im interested in seeing the glowing icing let me know
