Raj: I was just feeling blue.
Sheldon: Blue, as in depressed.
Raj: Well, not so much depressed; just lonely.
Sheldon: I don’t know what color lonely is.
Raj: What?
Sheldon: Red is angry; yellow is frightened; green is jealous; and blue is depressed. Perhaps, we can assign a color to lonely.
Raj: Nothing rhymes with orange; it’s probably lonely.
Sheldon: Alright. Come in. You look positively orange with loneliness.
