Here's an image I made after some experimenting to create 'approximate true color' Microscopic images.
It's from Spirit, sol 333. The color overlay was taken from Pancam sol 334 (3-filters used) images of the target.
There appear to be some darkgreenish patches resembling Olivine. Anyone has opinians? I realize the colors are not 100% as is but the overall look of these patches is green.

This is technique I tried about a year ago on Opportunity - it showed the blueberrys very well - it's a cunning idea. Of course - the MI has its own filter to fudge colour with as well

Yes you are right, the color filter of the MI has an effect too. Still, I was surprised of the resemblance to Olivine as seen in some lavarocks I have here at home.
This technique works pretty well right? Can I see your Opportunity MI?

WOW that was a long time ago

Color image from MI... Nix, you're a great chap!

Thanks Erwann Doug that is one magnificent image, I love the detail! We should make more of these man. Do you have others?

Nope - not done any since - but it might be cool to go back and hunt for some

Doug

It sure is worth the try!

User ERicdeParis at the space.com forum has a thread about a way he has imagined ( that's his words) to colorize MIs based on panoramic camera images.
