Blochsphere package - shading (brighter ball) [closed]

Question

I am using the blochsphere package and have a problem with shading of the drawn ball. Using the color white for the ball and opacity=0.7 makes it quite dark greyish. I dont want to turn down the opacity, since this would make the 3D effect of the shade vanish even more. But since I am already using white as a color I dont know how to make the ball look more white.

Can anyone help me out? I'd also appreciate any hints on which tags I could use here - tikz and physics seems quite inappropriate.
