AHello! I'm making a cake next month that I thought about filling with blue raspberry in keeping with the theme of the cake. I have used raspberry jam and jello in the past for raspberry filling but wondered if adding blue color would make it purple. Any ideas?

Well, probably need to just try it and see.

my idea is to use the berries whole if possible

I would recommend using only one dot of color, maybe two, before adding more, to get a lighter color and just add to it... try it! always try, you may find it was your best choice!

Thanks everyone. I guess I will just try it and see.  

AI believe Jello makes a blue raspberry flavor.

kool aid used to too -- i've used kool aid to color things in the past
