Active camouflage or adaptive camouflage is camouflage that adapts, often rapidly, to the surroundings of an object such as an animal or military vehicle. In theory, active camouflage could provide perfect concealment from visual detection.

Active camouflage is used in several groups of animals, including reptiles on land, and chepolo pod molluscs and flatfish in the sea. Animals achieve active camouflage both by color change and (among marine animals such as squid) by ,counter illumination with the use of bioluminesecence.

• . Scanning the environment:
  Sensors on the clothing detect the surrounding colors and brightness levels. 
•  Data processing:
  The microprocessors analyze the sensor data and calculate the optimal camouflage pattern. 
• Color adjustment:
  The display panels within the fabric activate to display the calculated color and pattern, visually blending the wearer into the background. 

• Superior Concealment:
  The primary advantage is the ability to seamlessly blend into diverse environments by adjusting to the color and texture of the background, making the wearer much harder to detect visually. 
• Increased Situational Awareness:
  Soldiers or users can rapidly adapt their camouflage to changing environments without needing to manually switch uniforms, allowing for better situational awareness and tactical flexibility
• . Improved Survivability:
  By minimizing the visual signature, adaptive camouflage can significantly increase the chances of survival in combat situations by making it harder for enemies to spot the wearer. 

• Technical complexity:
  The technology behind adaptive camouflage often requires intricate sensors and actuators to react quickly to changing environments, which can be expensive to develop and maintain. 
• Power requirements:
  The electronics needed for adaptation may require a significant power source, potentially limiting the duration of use on a single charge. 
• Environmental limitations:
  While effective in certain environments, adaptive camouflage might not function optimally in extreme conditions like dense foliage or highly reflective surfaces. 

Asia, particularly growing countries like India and China, has seen a significant rise in the military sector. In the APAC region, defence budget is increasing at one of the fastest rates throughout the world. Combined with the need to prepare military soldiers for modern combat, large sums of money have been invested in new military equipment as well as improved military apparel. Asia Pacific leads the worldwide market demand for military, smart textiles. Europe and the US come in second and third position, respectively. The market of military textiles in North America is expected to grow as the nation’s textile sector expands. The textile industry employs 6% of the entire manufacturing workforce in Europe. The United Kingdom spent 21 billion pounds in 2019-2020 in this sector. Thus, the market in Europe is predicted to grow as the textile industry in Europe expands.
