Hi @danno11

I suspect that the name turns red when shapr3D computes something tendentious in the geometry.  
It can be related to excessive surface curvature or zero width bodies.  
In the video bellow, the body’s name turns red when I twist the part by 120 degrees, which generates huge deformation on the surface. At 110° rotation, the part’s name is black.
