The average length of the common chameleon is 20–40 cm (8–16 inches), with females often being substantially larger than males.
The colour of the common chameleon is variable, between yellow/brown through green to a dark brown.
Whatever the background colour is, the common chameleon will have two light coloured lines along its side.
It has a small beard of scales and some small hard scales on the top of its back.
 Many assume the color changes undergone by the chameleon are a result of its attempting to camouflage itself, when in reality the chameleon changes its color as a response to light and temperature stimuli and as an expression of its emotions (like chameleon body language).
Often when caught for analysis, the chameleon may turn a dark color.
Their colors are also important for intraspecies communication, especially during the mating season.
