How To Mix Paintbrush Stroke?

[spectromagic fan]

Does anyone know how to make the Paintbrush Stroke drink that is served in Animator's Palate? My adult DS loved it when we were on our cruise in July. We've seen what's in it from the menu, but can't seem to mix it right. I'd love to surprise my DS with one when he comes to dinner some evening. If anyone knows how to mix it, I'd really appreciate your help. Thanks!
