I was inspired by this sculpture by Hans-Jörg Limbach:

But I have a totally different styling in mind for my design; I want to explore color gradients over the faces of the underlying mesh geometry like that done by Matthew Plummer Fernandez for his 3D printed models.

I created a tool in Processing called Hemesh Colorizer. So now I can manipulate and colorize models and then export them to VRML ready for color sandstone printing.

Here is my first attempt using a blue to black gradient:
index.php?t=getfile&id=37468&private=0

I roughed up the vertices for the hands to give the mesh more texture, but I think I might have gone too far.
index.php?t=getfile&id=37469&private=0

I'm going to be trying different color gradients and different algorithms for coloring the faces of the model mesh.

I'm playing with various color schemes. This version might be a bit too much. I think something subtle will work best with this sculpture.
index.php?t=getfile&id=37625&private=0

Here I'm alternating between shades of a color. It makes it look like a surface texture.
index.php?t=getfile&id=37626&private=0

The most promising version I think embeds a colored light rendering onto the faces of the underlying mesh. So it has a permanent light and shadow effect.

As long as the lighting and shadow is baked into the texture, yes, otherwise, no. A shadow on the model from lighting in your software rendering programme will not appear on the model unless you bake it in.
