- A chameleons skin changes color to communicate. It also changes due to temperature, light, and mood.
- The transparent outer skin is made of two cell layers.
- these contain red and yellow pigment or chromatophores.
- cells that give skin color
- below chromatophores are the cell layers that reflect blue and white
- then theres a layer of brown melanin
- causes skin to darken
- levels of external light, heat, and internal chemical reactions cause thes cells to expand and contract
