An approach for negating white's advantage

Or just play as both black and white... That is what they do in tournaments to balance the advantage.

Well sure, if there are multiple games. I'm talking about generally, on the individual game level, how to recognise the advantage...
In an individual game what is the point of scores other than win, lose, and draw? Scores are for tounraments which have multiple games.

Well, maybe there is no point! As I said, I was just fooling around to see what the points should, in theory, be worth, I'm not advocating an overhaul of tournament scoring... which obviously is that way for a reason!

The point seems to be that there could be multiple games, as in a tournament, but with each pair playing only one game. Maybe 11 players, 10 games, round robin format, each player plays five games as black and five as white. Sure, you could double it so that each combination plays both ways, but if time is short, then this may not be possible. Well, now that I think about it, the balance means that any advantage you get by winning as black is compensated by losing as white, so maybe here it would not matter. But in a larger pool, as we have here in Chess.com, with no guarantee of balance, it could be worth further consideration.
Fair enough.
The biggest problem I can see with something like that is that it is really difficult to actually quantify the advantage of white moving first. Even with statistics, theory changes over time which can change the actual value of going first. Even if you could quantify it you would have to requantify it every now and then to keep the point of equalizing the colors valid which is much more work than just making sure each player plays both colors equally.
