Chromatic Empathy

Hazel is a regular girl, at least that's what everyone else sees.
She's a specialized Mental Erosion Psychologist trained for Negotiation, that is her job title. But in actuality, she has the ability to discern people's true emotions, simply by looking at them. How?

Hazel can literally see a person's true color.

However, she can't decipher a person's complete emotion on color alone. As she meets people she learns to see people's feelings without the aid of her power and perhaps one day, she will be able to see her own.
