Lands are colorless so if you could put in different lands of colors your commander isn't you could technically run all 10 orig duel lands and 10 shock lands etc etc.

Color identity isn't derived simply from card color, it also take into account any colored mana symbols on the cards themselves. Basic lands, let's say a {Mountain} for example, literally have the text "{T}: Add {R} to your mana pool.", regardless of whether or not you see it on the card.

I personally think the colour identity rule is super redundant with the mana production restriction. Just keep the mana production restriction and let red decks run {Ancient Grudge} if they want to and any {B}/{X} or {U}{X} deck run cards like {Nightveil Spectre}.

That's blasphemy. Keep it up
