As far as my research shows you'd need electron microscopy analysis of the minerals. It looks like a job for a lab. Even then it would speculation. Kaidun would have to be present because Phobos and Deimos are captured asteroids themselves. Good luck.

Yes, it is. It's like pressing your fingers against your eyelids and seeing amazing geometries. It no longer works for me I suppose because of my age? I had a friend with a box attached to eyeglasses. When I wore them he fired up the box and I saw colors and geometries that were spectacular...

I'd do a fact check on that. In fact, I did and it's not true. 20/20 vision or better is what you'd need. That, and good peripheral vision. And night vision. Colorblind people are more sensitive to bright light and even a rifle flash can produce black or purple spots in their eyes...

But aren't they just seeing frequencies of what we call light? For instance; why is there no magenta in a rainbow? Birds, insects, and fish in the dark zone see in the UV spectrum but they still see colors although sunlight doesn't penetrate the depths. All heating coils produce the same hue...

Has anyone mentioned the standard test of a simple magnet?

Agreed; it's how sighted organisms distinguish dangers, poisons, threats, and mates. When I was young I could read only 5 of the 38 Ishihara color plates other than the two neutral standards. Now that I'm in my seventies I can't read any of them. I had no idea I was RG color blind until I was...

You're quite correct, we have cones that give us the illusion of color. But nothing is actually colored. We simply interpret shades of gray as color. There is only light and the absence of light to various degrees. Are you a tetrachromat?

Color doesn't exist. Only the totally color blind see the world as it really exists. Maybe that's why B&W photography is so fascinating.

Yes, I have. I'm glad I stumbled onto this forum. Great job of creating a worthy spot for research.

I love research and tend to use it in my stories. Although fantasy, I like a dose of factual truth. The more science is used in a story, the more engaging it is. I'm presently working on three storylines. I have published one fantasy; Bluestone Standing - Rosedog pub. But it was rushed and...
