They should. Since Pete already has his dad's green eyes
pretty sure he dyes his hair for movie
Here in the manhwa pete has almost the same hair as Josh but in the novel
Spoiler
pete got to know chase was his papa because of their hair color because pete thought they have the same hair
Dude. The artist definitely didn't do a good job of presenting that. No need to keep going over it. Sometimes they shift the palette and make even Josh's "brown hair" looks light. In the one kiss scene I almost couldn't even tell who was who?!? It's the art and not the representation. In almost ALL omega verses the child/ren almost always had one characteristic from the dad and one from the omega mom so that's no contest. Unless they specifically make it not so. But thanks for the *spoiler* anyways.
In the novel pete and chase have the same hair color
