ABSTRACT A system for providing a visual color display of multi-spectral and/or multi-sensor data particularly that provided by a trichroic infra- red scanning system, which includes the assignment of visible color signals to such data in a manner to maximize color discrimination of the viewer and allows the use of a conventional color display, particularly a CRT, to produce a real time color picture of the image that the data represents. The system includes several color guns each of which is capable of producing a beam current, with at least one gun for each primary color to be displayed. Several operational amplifiers, each corresponding to a respective one of the guns is provided, each amplifier having an input capable of receiving a video signal which corresponds to the infrared signal and an output. A feedback loop is connected between the output and the input of each operational amplifier respectively, incorporating in the loop a single color gun which is driven as a feedback element of said amplifier, a result of which is the production of a beam current by each gun which varies linearly as the video signal to the amplifier varies during image production.
