Agama

The agama is a species of small and brightly colored, desert-dwelling lizards. The agama is accustomed to the extreme temperatures of the desert and remains active even during the heat of the day. Its distinctive colorful scales are constantly changing throughout the day.

"But of the following you shall not eat... the Agama."
Leviticus 11:29

Chromatic Empathy. The agama's vibrant rainbow skin will change colors throughout the day. Unlike the chameleon, who uses this ability to blend in, the agama has no control over this change, and its color is always a reflection of its mood, using a variety of vibrant colors to reflect its various emotional states.

Agamas as Familiars

If a player character chooses an agama as an animal companion or familiar, the agama may start to change colors as a reflection of its master's mood as well as its own. At the discretion of the GM, player characters may even be able to train their agama to detect emotional signals from nearby humanoids, changing its color in response to the emotional temperature of a room or situation.
