adding some color :/

Hi guys i have created and rigged a mouse and i want to start animating it but first i wanna add some color my problem is that i simply dont know where to start and what process to use
the whole of the model is made of only one primitive (apart from the tongue)so i cant add differant materials to differant parts of the mesh (and if i can i dont know how)
i need suggestions
ive not tried uv mapping and i dont wanna just create furr using particles because i cant seem to get it to look right for short fur like that of a mouse so i decided against fur untill ime better at blender
i have adobe photoshop and paintshop pro
any suggestion guys?
thx in advance
