Hi there, 

Does anybody know how I can get this kind of purple on my fondant? I'm actually making a Vikings themed cake and I've never got this color before on my fondant, and I know for fact that dark colors are actually hard to get. Any suggetions? Also, if you guys have any other suggetion on this type of theme, it is more than welcome :)

start with a very bold purple that is fully developed, then add royal blue a little at a time
