re: Why did you just lie?
MERs have been sending us B/W images because NASA/JPL sent B/W cameras and use filters to make color images. In a sense they have been sending us color images all the time. One of the things Doug does is combined the filtered images to make colored images. Really cool color images! He is an asset here where you often are not.
You sometimes sound like a very big child with silly questions about stuff and it ticks people off. That in fact might make you a troll of sorts.
