I want to create a radioactive torus. First I think I need to change/set a color. I've created a torus and then (in material properties) a changed in Edit mode to green (see the snippet below).

I've also changed Emission to RGB green. Not only that the emission doesn't work, even the change color doesn't work: it's not green but still gray.

What's wrong with my Torus?

    $\begingroup$ I think you can't see the material in Solid mode, you need to switch to Render mode, if you want to change the color displayed for this object in Solid mode, go in the Material tab and Viewport Display > Color $\endgroup$

    $\begingroup$ @moonboots I have indeed found the Viewport Display. But it cannot be changed it , it changes back to white color whenever I change it to green one. Also I cannot find the solid and render modes at all in my opened Workspace. Everything (both the cube and torus) is still gray :-( $\endgroup$ Commented Jun 20, 2020 at 13:32
  • $\begingroup$ the Solid and Render mode are on the top right of your 3D View window (small sphere icons), you mean you can't activate them? $\endgroup$

  • $\begingroup$ @moonboots WIth your advice I've found the solid mode. However, both objects (the torus and cube) look still gray though Viewport Display is really green. PLEASE SEE MY EDIT FOR SOLID MODE in my OQ. What shall I do now? I'm a complete beginner to Blender! Thank you. $\endgroup$ Commented Jun 20, 2020 at 14:13

1 Answer 1


You have 2 materials in your material list, the one you've assigned is blank, you need to assign the other one (or simply delete the first one):

  • $\begingroup$ I have created a new file .blend because I do not know how can I delete one material. Now the color works, but the Emission doesn't: <img src="https://blend-exchange.giantcowfilms.com/embedImage.png?bid=PeSKgd9G" /> It should look radioactive like! $\endgroup$ Commented Jun 20, 2020 at 14:54
  • $\begingroup$ It seems to work fine in Cycles, I can't use Eevee on my computer, maybe someone will find the answer ;) maybe try some beginner Blender tutorials to learn the basics because you seem a bit lost for the moment $\endgroup$

  • $\begingroup$ The point was that I should have checked the material preview on the top right side and it works fine now! Thank you. $\endgroup$ Commented Jun 20, 2020 at 15:05
