Well, they are sort of different colors
True. It might be a stretch, but most of the sins have equals/opposites in the Emotional Spectrum.
Pride, Envy, Greed, Hatred, Laziness, Selfishness, and Injustice
Or: Pride, Envy, Greed, Anger, Sloth, Gluttony, and Lust
Greed-Greed (or maybe Gluttony, since wanting everything and wanting to consume everything aren't exactly the same)
Fear- Envy? (You could say that the opposite of fearing someone is wanting to be like them)
Hope - Selfishness (Gluttony?)
Love - Pride
Compassion - Injustice (Lust?)
Hope and Compassion may be the toughies with this one.
