So I was cleaning up an object in blender (mold I'm making of an eyelid to 3d print and pour silicone into) and things started going haywire. I filled a hole in some faces and the new face became purple (In solid mode, whether in object/edit mode) and I read online that could be because the faces didn't align properly. So anyhow I selected everything and recalculated normals, and now my mesh is dark grey (Pictured)
I read that dark grey faces could be directly because of the normals (make sense) but I can't fix it! I'll recalculate them, look at them in face orientation mode, etc.. and they're still dark grey. Help!
