Change color of wireframes manually.

What's that supposed to mean?

Please Explain Yourself.

I believe you mean the color of the wire in the 3d view...?

sombody else was playing with changing it (nothing nontrivial, but questions must be anwered, like will it be saved, and how, and where will the interface to it be)

if you are reffering to in renders, the wire is the color of your textured material
