Hi Rich,
> Why does the object have to be a mesh for a gradient to be applied? Confused!
Sorry I don't quite understand what you are referring to here - you're talking about some other software here and not MoI in particular, is that correct?

Yes sorry I was Michael - Rhino via Grasshopper. In that case, it appears that each polygon has a different colour within the mesh. I think Gouraud was what I was getting at, the gradient has to be interpolated to give a smooth look...I don't quite know how to approach this predicament! Does anyone know of any softwares that will allow me to play around with such shading using open nurbs objects (pipe dream)?
This is all very interesting thank you!

Hi Rich, look for things like "false color" or "vertex colors" something like this:

You want something that will let you specify colors per _vertex_ rather than a per _face_ color value.
Most mechanisms that allow you to supply color information at the per-vertex level will also handle interpolating the colors along the interior of the polygons that connect the vertices.
