I found this "true color" images of the spherules, it uses 3 images with L4 L5 and L6 filters and the corrections looks almost perfect
(the calibration seems to be almost perfect with L4 L5 and L6 filters

The terrain in true colors (from opportunity day 11) is really interesting

1. The just emerging ones are ALL white.
2. ALL the small debris are blue.

The "minerals" ) spherules are turning from white to blue when they fade, Oooops could minerals grow and die ?

On the microscopic images faded spherules (and pieces of faded spherules) are quite evident compared to the "budding" ones.

I know that most of you just can't admit, or even envisage, that these spherules are life. Let's try to forget what we think we know, we are probably at the stone age of sciences, let's be humble !

Most of us were prepared to the discovery of life traces, but why should life had disappeared ? What do we know about life as a phenomenon ? Nearly nothing, let's be humble ! Life may have perfectly adapted across millions of years !

Why not ? )

We should keep in mind that Einstein had put imagination ahead of knowledge.
