This is a difference yes, but it is an irrelevant difference because it doesn't effect anything.
There are two kindergarten classes. Class "Blonde" has 90 blond kids, and 10 strawberry-blonde kids. Class "Brunette" has 98 brunette kids and 2 kids with auburn hair.
Class "Blonde" has the newest toys and games, they get 1 hour for recess, they have 8 teachers, and they get private tutors available to them. Class "Blonde" kids are expected to wear blue shirts every day.
Class "Brunette" has hand-me-down toys and games, they get 30 minutes for recess, they have 5 teachers, and they can only get tutoring if they apply for and are approved. Class "Brunette" kids are expected to wear blue shirts every day.
The redheads in school are "transclassed". The strawberry-blondes dislike blue, and really strongly want to wear red shirts. The auburn haired kids detest red, and desperately want to be seen in blue shirts. In an actof compassion, the school administrators decide that transclassed kids can choose whichever class they feel most comfortable in.
The auburn kids join Class "Blonde". They now have access to newer toys and games, so even if they end up getting the oldest of the Class "Blonde" games, they're better than the games they used to have. They now get more time with the teachers than they used to, so even if they're the last ones to get that attention, it's still a win for them. Plus, they get blue shirts. They still feel a little bit awkward, because every time there's a class photo, they stick out a bit, so both of the Auburn kids lighten their hair so that it looks more Blonde and they fit in better. All in all, they are satisfied with the situation.
The strawberry-blondes join Class "Brunette".
Two of the strawberry blonds dye their hair a nice rich brown, play with the same toys as the original brunettes, play the same games at recess, make good friends with the original brunettes, and decide that it's very unfair that Brunettes don't have the privileges and benefits that Blondes do, and think that strawberry blondes and brunettes should work together to change how the school works.
Five of the strawberry blondes dye their hair crimson, so that in black & white photos it doesn't stand out. They play with the same toys as the brunettes, but they tend to try to get the best of the old toys before the brunettes do. But they're willing to share most of the time. They get along fairly well with the brunettes most of the time, but they get offended if any of the brunettes refer to them as redheads or as strawberry blondes, but mostly just grumble. They are aware that Brunettes don't get the same privileges and benefits as Blondes, but it's not important to them and they don't care. They really just want the blue shirts, and they don't really have any interest in making the lives of Brunettes as a whole better, and they get annoyed when Brunettes talk about the disparities they face relative to Blondes.
Three of the strawberry blondes decide they like their hair as it is, but they still want people to refer to them as brunettes. They think it's a horrible insult to be referred to as strawberry blonde, and they think anyone who uses that term is a bad person who shouldn't be allowed to have recess or play with any of the toys. They liked the toys that the Blondes had, so they push ahead of other kids in class and take the best of the old toys for themselves. Because they felt mistreated by the Blondes, they believe that Brunettes should give them the best toys and games to make up for it. They think education is important, and they got their parents involved with the school to ensure that they get as much time with the Brunette teachers as they used to. They acknowledge that this means the original brunettes will get less attention from teachers, but they feel they are entitled to high-quality education, so if the brunettes are unhappy about it, oh well. They can find a different class. The school administration said they could join whichever class they wanted, so there's nothing those brunettes can do about it.
