the shading colors in the options panel.
In addition to the face
curvature display, the absolute values for minimum and maximum curvature are
displayed in the Properties panel.
The
curvature with the smallest radius is shown in the maximum color (red is the
default). The curvature with the smallest radius, or no radius, is shown in
the minimum color (gray is the default).
