Thats actual a psychological one with the sports and services. Red is commonly associated with blood and violence and is a thing to be feared, while blue is calming and serene. Naturally sport teams would want to intimidate the other team and services would like to seem more appealing and calming to its customers
Pink actually used to be given to newborn boys but it switched over to girls at some point for some reason. And color association is a huge thing too. Banks use black and green for logos bc black insinuates class and success while green is an allusion to money and wealth. Red and yellow tends to make people hungry which is why restaurants have logos with those colors. Its a graphic design thing meant to invoke a thought in someone's mind to associate the thing with. Which is why boys are blue and girls are pink.
It switched because Hitler used the "Rosa" pink triangle to mark the gay men that he killed. After that, nobody wanted to mark their male infants in pink.
It was just a joke about cultural behavior. We do strange things. Why do we put candles on birthday cakes? The Bunny/Egg/Easter connection? Celebrating the birth of our Nation? Lets blow shit up. Our team won? Lets riot! WTF
This sounds a bit like what happens in Brave New World: social class is determined before you're born and you later have to wear a jumpsuit in your class colour. From highest to lowest social rank the colours are grey, red, green, khaki and black.
For those who don't know what Brave New World is, it's a really good and thought-provoking book.
