What color green do you think was used on these cupcakes in the icing? It was posted in 2005.

I would use neon green with maybe a hint of lemon yellow if the neon alone didn't get it where I wanted    

Several brands now carry neon gel colors, I like the hobby lobby store brand for colors 

Thanks mccants! We don't have a Hobby Lobby here, but I'll check online. I'm assuming the web is done with stiff BC or perhaps RI.

the web could be royal with gum arabic added for shine but it looks like black licorice too

I was thinking black licorice too from another one I saw like that. Cute cupcakes!

Leaf green would probably also work.

Thanks Magda! mccants if I make the swiss buttercream at what stage do I add food coloring and do I need any special type of coloring for it?
