Help with Picking Colors for multiple characters

[Gabby Correia]

Hi all you clever, creative people. I am hoping for some advice and input.
I am starting on a new book, but there is no main character. Instead, there are 6 diverse characters that all feature on different pages in the book.
I need help picking colors that are unique to each character, but still compliment each other.

Here is what I have come up with so far. What do you guys think? Any comments on other parts of the design and how I can improve the characters are also welcome.
Thank you

@Gabby-Correia I think the colours are fine Is there a reason you're using a warm grey for the eyes instead of white?

[Gabby Correia]

@Braden-Hallett Thank you, I will be rendering these (won't be flat color), so I usually use grey for the eyes so that I can add white highlights at the end. I very rarely use pure white

Started on the rendering of the first character

@Gabby-Correia hi! I like your colors. I think you made a great choice. My one issue is with the Muslim boy. His features look too old. All the other kids look their age but he looks like an adult in a boy's body. Maybe you can soften his feature like rounding his face and eyes more?

[Gabby Correia]

@Nyrryl-Cadiz thank you, yes, I agree with you! I think his nose and eyebrows probably also play a role in making him look older.

[Nyrryl Cadiz]

@Gabby-Correia for me it's the shape of his eyes and his lack of a jaw

[Gabby Correia]

@Nyrryl-Cadiz does this look better? Still very rough as you can see

[Nyrryl Cadiz]

@Gabby-Correia looking good! maybe shorten his eyebrows as well like the other kids. it can still be thick but shorter

[Gabby Correia]

@Nyrryl-Cadiz Yeah! Ok great, thank you for your help

@Gabby-Correia they look so good! I especially love the hair. The little extra whisps really sell it.

@ambiirae Thank you so much! The wisps are my favorite part to paint
