 When triggered by melanophore-stimulating hormone and other hormones, the melanosomes of the melanophores partially cover the other skin pigment cells, giving the anole a darker or browner color.In most cases stress results in a darker/browner color, but in the aquatic anole, a species that is dark brown with a barred pattern and light brown stripes on the sides of its body and head, stress results in paler brown upperparts and the stripes turn pale blue-green.Their colors during the night when sleeping often differ distinctly from their colors during the day where awake.
