Active camouflage technology, both visual and otherwise, is a commonly used plot device in science fiction stories. The Star Trek franchise incorporated the concept ("cloaking device"), and Star Trek: Voyager depicts humans using "bio-dampeners" to infiltrate a Borg Cube without the antagonists realizing they are there.

Multi-spectral camouflage can be applied to individuals, to vehicles, and to buildings. It can take the form of specialised paints or camouflage nets that provide conventional camouflage, reduce the amount of heat given off by an object, and alter the shape and size of its radar signature.
An operational, non-fictional cloaking device might be an extension of the basic technologies used by stealth aircraft, such as radar-absorbing dark paint, optical camouflage, cooling the outer surface to minimize electromagnetic emissions (usually infrared), or other techniques to minimize other EM emissions, and to minimize particle emissions from the object.
Other well-studied examples include the cookiecutter shark (Isistius brasiliensis), the marine hatchetfish, and the Hawaiian bobtail squid. [6] More than 10% of shark species may be bioluminescent, though some such as lantern sharks may use the light for signalling as well as for camouflage. [15]

And like all other examples of camouflage, aircraft patterns vary widely between countries, aircraft, historical period, and the location that the aircraft was being deployed to.
For example, there are other parts of the light spectrum which are in common use today. The microwave spectrum is employed by radar , cell phones , and wireless Internet . The infrared spectrum is used for thermal imaging technologies, which can detect a warm body amidst a cooler night time environment, and infrared illumination is combined ...
Adaptiv is an active camouflage technology developed by BAE Systems AB to protect military vehicles from detection by far infrared night vision devices, providing infrared stealth. It consists of an array of hexagonal Peltier plates which can be rapidly heated and cooled to form any desired image, such as of the natural background or of a non ...
