Barry,
I've never said that there is NO life on Mars, only that if there is, we haven't found it yet and not to expect anything but the microbial variety. I've also said we should not expect to find life on the surface of Mars expect possibly in rare, well-protected micro-climates associated with hydrothermal activity. Otherwise we'd best be looking below the surface.
But on the subject of photosynthesis or lichens on the surface of Mars - this is simply silliness.
My point about the color of Mars is that its not all that important. We have close approximations already. So what if we can fine tune the color knobs a little better? But suggesting that finding things green in color on Mars is evidence of photosynthesis at work is just plain silly.
