colour composition A remote-sensing term referring to the process of assigning different colours to different spectral bands. The colour picture formed by this process is called a "colour composite" (a colour image produced through optical combination of multiband images by projection through filters) and is produced by assigning a colour to an image of the Earth's surface recorded in a particular waveband. For a Landsat colour composite, the green waveband is coloured blue, the red waveband is coloured green and the infrared waveband is coloured red. This produces an image closely approximating a false colour photograph. Colour composite images are easier to interpret than separate images recording different wavebands. US national experimental crop inventories are based upon visual interpretation of Landsat colour compositesfarvesammensætning
