Do salamanders change color?

Tiger Salamanders are highly variable in color. Some have a dark background of black, blue, green or gray, with bars, patches, or spots that are white, yellow, orange, or even black. Others are the reverse, having a lighter background with a darker pattern. The colors vary even among subspecies. The vent is usually yellow or white, flecked with green or black. Colors may change as the salamander ages. There are some albino forms, as well
