I've played the game a lot and there are definitely five emotions shown for characters with their corresponding background colours.

Blue whenever they're neutral.

Green/Light Blue (depending on the game) whenever they're happy.

Dark Blue whenever they're sad.

Red whenever they're angry.

and

Bright Orange whenever they're surprised.
