After a lot of hunting I think I have found one image that has been produced as a combination of L4, L5 and L6 filters.



Made based on perceptual data of the eye's sensitivity to light in the filter spectra. From images;

This would appear to be the closest image yet to what would be seen if you were stood on Mars looking at the surface.

As you can see this particular image is the marks left from the airbags on the soil after Spirit's landing.
