Green cheeks are still green cheeks regardless of colour, very much like poodles are still poodles whether they are black white red or pati coloured. It doesn't affect their Temperament.
I have an amazing pineapple green cheek (albie) who is the sweetest little snuggle bug one moment and then a terrible terror the next. He's super smart (like, using tools smart) and Sassy and funny, but he also has an absolute temper on him where he's very quick to use his beak to put me "back in line" for what ever wrong I've commited. If you look through my post history, you'll see my ups and downs with him. His absolute favorite thing in the world are his hand snuggles (where he snuggles up to my cupped hand and will happily fall asleep). Despite our ups and downs, he is easily the most incredible, loyal, loving animal I have had the pleasure and privilege of having as a companion, and I say this despite having the most amazing Boston Terrier who passed away 2 years ago (he was a truly amazing dog, but the relationship I had with Oliver was on a completely different level to what I have with albie)
All Species have a behavior/personality generalities that they can fall into, but there will always be individuals that don't fit in with that for various reasons. Some don't like to snuggle but are happy to hang out, some are super loud for what's considered a quiet conure species, some are super stubborn for training whole other are easy,you get the idea.
