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?
EDIT for solid mode
