这个我也不知道，也许根据温度变化？因为李冰他们家小翠夏天很翠冬天就很灰黑。。

Change of color
Some chameleon species are able to change their skin colors. Different
chameleon species are able to change different colors which can include pink
, blue, red, orange, green, black, brown, light blue, yellow, turquoise and
purple.[18]
Color change in chameleons has functions in social signaling and in
reactions to temperature and other conditions as well as camouflage. The
relative importance of the classes of function vary with the circumstances
as well as the species. Color change signals a chameleon's physiological
condition and intentions to other chameleons.[19][20] Chameleons tend to
show darker colors when angered, or attempting to scare or intimidate others
, while males show lighter, multi-colored patterns when courting females.[
citation needed]
Some species, such as Smith's dwarf chameleon, adjust their colors for
camouflage in accordance with the vision of the specific predator species (
bird or snake) that they are being threatened by.[21]
The desert dwelling Namaqua Chameleon also uses color change as an aid to
thermoregulation, becoming black in the cooler morning to absorb heat more
efficiently, then a lighter grey color to reflect light during the heat of
the day. It may show both colors at the same time, neatly separated left
from right by the spine.[citation needed]
Mechanism of color change
Chameleons have specialized cells, chromatophores, which contain pigments in
their cytoplasm, in three layers below their transparent outer skin:
1. The cells in the upper layer, called xanthophores and erythrophores,
contain yellow and red pigments respectively.
2. Below these is a second layer of cells called iridophores or guanophores;
these contain guanine, appearing blue or white.
3. The deepest layer of cells, melanophores, contain the dark pigment
melanin, controlling how much light is reflected.
Dispersion of the pigment granules in the chromatophores sets the intensity
of each color. When the pigment is equally distributed in a chromatophore,
the whole cell is intensively colored. When the pigment is located only in
the centre of the cell, the cell appears mainly transparent. Chromatophores
can rapidly relocate their particles of pigment, thereby influencing the
animal's color. Chromatophores change because the cells get a message from
the brain.[22]

上面是从维基百科上摘的。
我觉得，如果把变色龙的眼睛蒙上，它还会因情绪变化而改变体色，也会为了调节自身
体温而改变体色，但会不会根据环境来改变体色就不知道了。
说不准变色龙能用眼睛以外的器官来感知周边环境，纯瞎猜。
