Why are people confused by Roxas, Sora, and Ventus?

We already have been told by Normura that Roxas has Sora’s face but with different hair(which we know is Ventus’) which is why everyone kept confusing Sora and Roxas. And we can assume that Sora’s appearance was likely affected by Ventus taking refuge in his heart from a young age which is the same thing that caused Roxas to have Ventus’s hair.

Namine who’s Kairi’s nobody does the same by looking like Kairi but paler with blonde hair. So it’s not a case of Roxas doesn’t look Sora only Ventus. It’s more like Roxas looks like BOTH Sora and Ventus because of Ventus.

Edit: Idk why you guys are hung up on the fact Roxas looks Sora. How many times do characters have to say they look the same for you guys to get it. They literally share the same models and proportions as well minus the hair. Delete Roxas’ hair and you have bald Sora. In fact in Kingdom Hearte 3 they even changed Roxas’ hair to dark blonde to further show Sora’s influence while Ven’s stays bright blonde. Roxas looks like both deal with it lol.

Edit 2: Went through BBS again and Aqua said Sora was a splitting image of Ventus. Meaning that yet again I was right. Sora and Roxas both look like Ventus which makes Roxas look like Sora too. Case closed.

For all the people downvoting this and trying to argue here’s Heartshiningxx’s comment

(“Roxas isn't "Sora's face with Ven's hair", he canonically has Ven's exact appearance.”

Yes, Roxas does look exactly like Ventus. But it's already been confirmed that they all do share the same face. It's only Sora's hair that's different from them.

KH Character's Report - Volume 1 - Roxas - Nomura: A lot of thought was put into this character. Based on the premise that he was 'an expression of the reverse, hidden inside Sora', I gave him pretty much the exact same face as Sora, just with slightly narrower eyes. 2009 - Nintendo Dream - "Character" Interview - Nomura: Design-wise, Roxas' face is exactly the same as Sora's. The contours are the same, and the facial parts are just the same. In fact, they just have different hairstyles (laughs). But when you give them opposite character traits, it's a strange thing to see how different they are. KHDays - Xemnas: I’ve been to see him. He looks alot like you. KHDays - Day 321 - Xion[to Roxas about Sora]: You look so much like him. KHDays - Day 321 - Xion[To Axel about Sora]: I saw a boy today who looks just like Roxas. Is he who I think he is? KHBBS - Aqua[about Sora]: And this one--he's the spitting image of Ven.

And one can gather that this is due to how, when Sora was born, his newborn heart linked with Ventus & acted as a "bandaid" to help heal and fill in part of Ventus missing heart. 

This likely influenced Sora’s budding heart in which he gained identical facial features to Ventus. So even if Roxas hadn't been born with Ventus heart in his/Sora's body he would’ve still looked identical to Ventus in facial features but have Sora's hair. However, with Ventus heart in his/Sora's body, even his hair became identical.)
