===Relationship with environment===
The dewlap comes in a variety of colors, including yellow, blue, and red. It was previously believed that the color of the dewlap is what mattered most in interlizard interactions, but it has since been found that there exists a relationship between habitat light conditions and dewlap color.<ref>{{cite journal | last1=Fleishman | first1=Leo J. | last2=Perez-Martinez | first2=Christian A. | last3=Leal | first3=Manuel | title=Can Sensory Drive Explain the Evolution of Visual Signal Diversity in Terrestrial Species?

There have been many methods used to determine this. Persons et. al (1999) found that the probability of a dewlap showing being detected goes up with the contrast of dewlap against the background. They determined this by measuring the number of times a "positive response" of the lizard's eyes turning towards a flashed dewlap occurred among different background contrasts. Similarly, Leal and Fleishman (2002) found that the light conditions in which a lizard displays its dewlap affects the probability of it being visually detected. They did this by measuring the UV spectral reflectance of dewlaps in ''Anolis cristatellus'' lizards using a [[spectroradiometer]], then measuring the spectral sensitivity of the lizards’ retinal responses using electroretinographic (ERG) flicker photometry.<ref name="Leal, M 2002. pp. 351">{{cite journal | last1=Leal | first1=Manuel | last2=Fleishman | first2=Leo J. | title=Evidence for habitat partitioning based on adaptation to environmental light in a pair of sympatric lizard species | journal=Proceedings of the Royal Society of London.
