It's not. Colour refers to visible light, which is distinct from heat. Maybe you mean "false colour" images from a thermal camera, that assigns visible light colours on the basis of temperature (usually low temp=blue, high temp=red).
A false color image, made up of colors such as reds, yellows, and purples, can be more useful. In a false-color image of Niagara Falls, the calm water upstream might be black while the waterfall's turbulent water is bright blue.
Airplanes won't be very helpful, but satellites can look in most shades of the electromagnetic spectrum and analyzing a combination of false color composite images from visible light and the infrared spectrum one could isolate areas with good indications of ore bodies. However the most common way of finding ore bodies is by drilling, core logging and lab analysis
