What is E n h a n c e d C o l o r ?

We can enhance color images by showing each individual red, green and violet filter image in a full range of brightness from black to white. Instead of requiring that all the filters be treated the same, we can increase the contrast of each color seperately. This can show subtle color differences more clearly, but it can also lead to false impressions.

For example, areas on Io that appear whiteish at visible wavelengths (on the left hand side of the image below) look blue in an enhanced color picture (on the right), just because they are not as yellow as other regions.

    Okay, I understand true color and enhanced color. So what is false color?
