Here are the brushes for the cake. I started everything with two boxes of Wilton ready to use fondant. One is "natural colors" - light &dark brown, peach and black. The other was the pastel multipack with pink, blue, yellow & green. I marbled gel color into the blue (delphinium blue from the garden colors). I also have a bunch of pearl dust powders that I use to add some of the deeper colors on the pink/ blue / green etc, and some silver and a pearl one for shimmer.
By the way, rolled fondant tastes like crap. It's a weird sugary dough but not in a good sense. Just being honest. (Although my friend Poly makes her own, I believe, and I'm sure that tastes much better.) It's great fun to play with though.
