I have a 3-D object which I've converted to a very nice looking alphaShape object after getting the PixelIdxList and using ind2sub to get the coordinate of each voxel.
As awesome as they look, I really really need to change the color of some of the objects to anything other than the default green. Any idea on how to change the color?

You can grab the handle to the patch objects making up the alpha shape as the output from plot and then change whatever properties of it you want:
data = randn(100,3);
as = alphaShape(data);
h = plot(as);
h.FaceColor = 'b';

I'm sorry to bother you!
What if you wanted my graphics to have a regular gradient of color, like a rainbow. Rather than a single color.It could be like this picture, or even more beautiful.

Looking forward to your reply.

Not sure what you're doing, but a huge number of MATLAB graphics functions have a 'Color' input parameter. Check for that.
