Leaves

The leaves are turning colors very beautifully now.....in January??
But it isn't so that they change colors when temperature drops, and colder the better for nice colors? Well, here in Florida, it never gets cold enough in Fall, leaves never gets beautiful colors. So what happens now, in January, we keep having low temperature, that is equivalent to the Fall temperature in Northern area.....so leaves think that this is Fall and turn their colors???
