Entropy Judge
Recurring Bouts of Misanthropy
I'd argue that Squall isn't very Blue at all. Unless it directly pertains to his mission, he really has no desire for extra information and knowledge. Even when it does pertain, he often isn't particularly interested. Squall is, however, very White, even - perhaps especially as a New SeeD. New SeeD Squall wants everything to fit into nice, organized categories: Enemies are enemies, and the why doesn't matter. They go in the box. Superiors are superiors and to be obeyed, subordinates are subordinate and to do the obeying. Arguably, Early Squall is pure White, shading into Boros towards the midpoint.He's proud, conceited, ashamed at the same time; perpetually consumed by loneliness and social awkwardness and embarrassment. He has none of the stability or happiness or peace that White or Green bring. All the inventivity of Blue, the ruthless power of Black, and the fiery determination of Red are combined in his ideal model of himself and it's driving him miserable. But he is very, very good at killing things.
As for other FFVIII Characters ...
Zell is Blue/Red. Very pure Izzet, a whole lot of passion and a whole lot of knowledge, good with his hands and machines.
Selphie ... maybe pure Red? Not sure what else says, "I'm gonna drive this train full of rocket launchers off the tracks and see where it takes me!"
Quistis is definitely some flavor of Blue/x. Not Black, probably not Green. Don't know that she fits pure Blue, but she might.
Seifer is Red/Black in all its selfish, romantic glory.
Rinoa is Red, maybe Red/Green?
Laguna is definitely Red, might be Red/Blue.
Kiros is Blue ... maybe a combo?
Ward doesn't get a whole lot of screentime, but ... maybe White?
FFVIII, as a teen romance, is going to like its Red characters, so you could argue that all the younger characters are Red/x.
