I just want lots of positive role models children can relate to.
Okay, so the only thing I would say is the eye colors.
Brown is a dominant eye color over blue, so I would recommend changing some of the colors to a brown or hazel.
If you want realistic role models for children, making the characters more ethnically diverse may help. That way kids can see themselves in your characters. I appreciate the attempt at diversity but It isn't very realistic that in a cast of 12, only 3 of them aren't white. Try not to reduce those 3 characters to being the 'token' Latina, etc. If you are too attached to the characters and don't want to change them in a major way, then make sure the racially diverse characters you do are written with respect.
Also, minor nitpick but violet is not a real eye colour.
Red hair/blue eyes is actually a really rare combination, as is blonde hair/green eyes. Violet eyes are also exceptionally rare.
I'm not even sure violet eyes are even real tbh.
Maybe if a character is albino they could have purple eyes? Or red. And of course, this all assumes this takes place in a realistic world. Is the world fantasy, because then you have any combinations
I looked it up, and albino people can have violet eyes, and a few people do have them, namely Elizabeth Taylor was famous for having violet eyes but in the pictures I saw they looked more like a grayish blue.

No, Elizabeth Taylor's eyes were actually blue. The purple colour was created through a combination of makeup, lighting, clothing and stage effects.

Some eyes can appear violet under certain lighting as well. Most people that may seem like they have violet eyes actually have blue eyes.
To me the characters look pretty good but I’d recommend more hazel/brownish eyes, and a more ethnically diverse group? If you don’t want to change that about them, that’s fine with me. What I offer as advice you don’t have to take.
This link can also help for if you want to choose an eye colour in future reference (unless you plan on changing up these characters) since it has a lot of neat information about the eyes in it.
Yeah, unless it's a fantasy or a dytopian setting where genetics are modifiable (for example, my friend's world has very high technology, and her MC has orange and blue eyes) violet eyes are extremely unlikely, if not impossible. Maybe add some more ethnic diversity as well? Seems like a lot of white people, which I myself am guilty of in writing but trying to improve.
I think you should definitely do research on natural hair and eye colors. For instance, there are more types of blonde besides “blonde” and “dirty blonde”: including bleach-blonde and strawberry blonde. As for eye color, green and blue are among the rarest of eye colors (though having five blue-eyed characters in the group is possible, though unusual.) Also, make sure that eye and hair color correspond with their race. I like how you’ve added diversity into your eye color for the most part. I’m agreeing with everyone else on the violet eyes part. They don’t occur unless you are an albino, or from a fantasy world.
