Marine animals such as squid, cuttlefish, and octopus can display incredible patterns of colors by selectively contracting individual muscles to activate pigment-containing cells below their skin.

New semi-transparent solar cells use 3D-printed pillars to adjust color and light transmission without changing the solar material, ideal for windows and flexible surfaces. Using a 3D-printed pillar ...

A new study highlights a semi-transparent, color-tunable solar cell designed to work in places traditional panels can't, like windows and flexible surfaces. Using a 3D-printed pillar structure, the ...

I occasionally need to convert the background color of a particular image to be transparent so that the image looks better on medium with backgrounds of colors other than the image’s original ...
