Sol 2804 | Dec 14, 2011 - TRUE Color L456 Filter
For quite a number of Martian Sols "days", the Mars Exploration Rover Opportunity has been roaming the Endeavor crater conducting Panorama surveys and checking nearby outcropping. These composite images are considered "enhanced", and are done by four images, using the L2,5,7 filters. These are different then TRUE color shots, which use the L456 filters to try and capture the more realistic color of mars. ENHANCED images are used to help bring out geological detail in the landscape. In these images the sky appears blue, and it could be mistaken for a valley in the Utah, or elsewhere in the United States red desert. But, in act the sky of Mars is white.

As you can see from the image on the bottom left, the colors are more subdued and a whiter sky. Using True color composites, you can get an image closer to the what humans may see on Mars.
