For all intents and purposes, Ash is Red, and Red is Ash. Just like Gary is Blue, so much so that they look identical. Ash and Gary are literally just the anime's versions of Red and Blue, so I feel like the argument of "It's not technically Ash/Red" is kinda silly, especially if it's used to suggest 2B is more iconic, for example.
