How do I find all game object possessing the same name?

"GameObject.Find()" only picks one

Please do not recommend Tags to me, that's not what I need here

e.g.
Say I have 200 obj, 100 of them are named Blue and the other 100 are named Red
I want to find all the obj in my scene named Blue and Tag them Blue, find all the obj named Red and Tag them Red
Obviously I want to do all this in code instead of individually finding and Tagging all 200 objects myself in a scene where some of the objects are children of other objects

then iterate and if(name == "Blue")...
