Inconsistent behaviour when changing widget color of mesh clip plane

[machur]

Describe the bug, what's wrong, and what you expected.

I've tried to change the color of clip box around a mesh using plotter's add_mesh_clip_plane method. It looks like the behaviour of "wigdet_color" parameter is not consistent: with lighter colors the box remains white and only the arrow is painted, for darker colors the whole box is displayed in the defined color. Would you please advice how to set the color to the whole clipping box for lighter palette?

Steps to reproduce the bug.

import pyvista as pv

p = pv.Plotter()
p.add_mesh_clip_plane(pv.Sphere(radius=3, center=(0, 0, 0)), widget_color="red")  # pink
p.show()
