Dynamic
morphing of marine species to match with environment changes in color
and texture is an advanced means for surviving, self-defense, and
reproduction. Here we use colloids that are placed inside a multilayered
structure to demonstrate color and texture morphing. The multilayer
is composed of a thermal insulating base layer, a light absorbing
mid layer, and a liquid top layer. When external light of moderate
intensity (∼0.2 W cm<sup>–2</sup>) strikes the structure,
colloids inside the liquid layer will be assembled to locations with
an optimal absorption. When this system is exposed to continuous laser
pulses, more than 18 000 times of reversible responses are
recorded, where the system requests 20 ms to start the response and
another 160 ms to complete. The flexibility of our concept further
allows the system to be built on a variety of light-absorbing substrates,
including dyed paper, gold thin film, and amorphous silicon, with
the top layer even a solid
