I mean, if you want to go there, we can. After 1.e4 by far the most common choice for Black is one that breaks symmetry (1...c5). Same for 1.d4 (1...Nf6). Black, on average, chooses the asymmetric line against White's first move twice as often as the symmetric option.
That's true, and while it isn't given that the most popular lines are the strongest ones objectively, 1. e4 c5 and 1. d4 Nf6 are considered at least as strong objectively as 1. e4 e5 and 1. d4 d5 as far as I know. However, that doesn't contradict my initial statement, which is that black having the option (but not the only option) to copy white on move 1 is a reason that chess is well balanced.
How can one understand on a general basis that black is able to play non symmetrical moves against white's strongest moves and maintain a balanced position? Well, in the cases of 1.e4 c5 and 1. d4 Nf6, black prevents white from establishing a full pawn centre, thus securing himself the opportunity to mirror white's move 1 on a later move, for instance 1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 e5 or 1. d4 Nf6 2. c4 e6 3. Nc3 d5. That's not to say that black is dependent on being able to do this in all lines, but having the option is an important part of black's claim of equality.
The omatamix setup works similarly: blue/green have the option of mirroring red/yellow on move 1, but they have other options as well.
In bsrti setup, given that it is sub-optimal yet OK to play king's pawn for yellow, BG can copy any opening of RY and get away with it pretty much perfectly, and in case of double king's pawn that is probably advantageous for BG, BG still can play king's pawn albeit via a transposition.
