What you can do, is create a sphere, and assign a new blinn shader to it. Map a ramp to the color. Click on one of the circles beside the ramp, and under interpolation, click none. In the viewport, press 6 so you can see the texture in the viewport. Move the colors around until you get something useful.
Note: You may have the change the mapping direction from/to U or V in the ramp.
Imagination is more important than knowledge.
