Remove opaque tint in Viewport Shading Solid

Hi :slightly_smiling_face:
I wanted to create a quick visualization for a study project in blender and got it down pretty close.
My only problem is, that I want to remove the opaque tint an object leaves on the objects below it.
I am in “Viewport Shading: Solid” and used viewport materials andthe Sphere has an alpha of 0.1 to see the arrows underneath but tints the arrows below it.
I would like to have them in full color, if possible. But still the sphere to be a distinct color from the background.
Do I have to change to “Viewport Shading: Rendered” and change to nodes to achieve my goal?
Any help appreciated.

Edit: I could provide my .blend file, but apparently new users are not allowed :frowning:

Welcome to the community!

In solid view mode, you could make it work by selecting the arrows and check the “in front” option. Though, the arrows will also appear in front of other objects if there are any.

If you are in Eevee, you could flip the sphere’s normals to the inside (shift+n in edit mode, check the “inside” checkbox), then disable the shadows and activate backface culling on the material. However, that will make the sphere look concave. A similar effect could be achieved in Cycles, but it would need some more complicated node setup.

Finally, if you really need it to look exactly like you explained, you would have to render the sphere and the arrows separately and then composite them back together.
