Yes, they come in the skin colour and are totally unpainted, even the eyeballs are not coloured. You have to add in your own paint and make it anime styled. It's a totally different kind of painting from Gundam, and would require a different set of paint and brushes.

Although the Gundam kits come with stickers it cannot be compared to those of air brushed quality. I used to just use Gundam markers for my Gundams but after seeing what a friend can do with an air brush I got hooked and addicted to modelling : )

On another note, here's my collection of GSD gashapon figures. I actually got 2 stellars and gave one away. Pic's a little small as I took it with my phone camera.
