This paper discuss the Unmanned Aerial Vehicle (UAV) used for surveillance purposes and for dropping bombs in enemy headquarters. CAMOUFLAGE is defined as the blending of material with its surroundings in terms of colour in the surroundings. In Defence sectors their uniforms, vehicles, tools and tool boxes are camouflaged with the paint coatings. In nature the reptile chameleon changes its colour with help of different pigments stored under its skin. Primary mission threats do not stem from infrared or radar signatures, but from the amount that an UAV visually stands out against the sky. This concept such that visual mismatch can often jeopardize mission success and induce the destruction of entire UAV. To bring out the colour changes in UAV according to the region it travels. With the naked eye it can be caught down, but with this technique there is no possibility of finding the UAV with RADAR System and by naked eye. With the help of (OLEDs) organic light-emitting diode display, we are going to cover on the Visual Cross Section of our UAV. Colour sensors are used to sense colour in the surroundings. Altering the RGB values necessary CAMOUFLAGE can be achieved.
