How Do I Assign Color?

Hi all, I know this is technically not the place for this but I’ve tried the Blender forum and received no response. Is anyone here more Blender fluent than I am? I’m trying to make this sphere into an eyeball. I know I’ve done this before but for some reason my brain is spacing on how to actually do this.


I have the inner rings selected to be the Pupil. I thought in the past I just selected the rings and pressed “assign” but that doesn’t seem to work so I must be missing a step somewhere. Anyone know what I need to do? Any help is much appreciated. Thank you!

You need to add a new material using the + button and then press assign.
