It's great to explore Astrobin's gallery of photographs of the Mineral Moon (call it a hobby), but... I don't think there is a "true" or "well balanced" photographic rendition of the moon's colors. The boundaries of the colored regions look the same on all of the photographs, that's okay, which also means: these photographs could be used as reference to create a map of the moon's colors, but... the colors look totally different when two (or more than two) photographs are compared. Still, it's excellent material to "find the differences"! We have enough material to create some sort of catalog of the most colored regions of the moon's nearside (the most bluish crater, the most yellowish crater, etc...). While I'm into the colors of the moon, I would like to know if some of you, telescopic observers and photographers of the moon, still use Patrick Moore's so-called Moonblink Device (an optical contraption attached to the eyepiece to detect unusual and temporary color differences). What I also want to know. Is there some sort of digital program to create an artificial blacklight instead of the (slightly yellowish) white sun as lightsource? (say, what is he talking about ?!?!). Imagine the moon illuminated by a blacklight (a deep ultramarine blue artificial lightsource to show only the pure white, the vivid colored fluorescent, and the phosphorescent objects). Several minerals and rocks on Earth show wonderful fluorescent colors when they are illuminated by blacklights. I wonder if the lunar rocks and regolith, brought back by the Apollo astronauts, were illuminated by blacklights too, to see if perhaps "hidden" sorts of minerals appeared... I think our moon would look totally different if our sun was an ultramarine blue lightsource instead of a (slightly yellowish) white. A veritable mineral moon! Mmmmm... a very powerful beam of ultramarine blue light aimed at the nocturnal part of the moon's nearside, could show us a lot of colorful surprises! And... NO dear readers... I don't need hallucinogens to think "colorful". I just think a little bit further than the usual or "grey" way of thinking. |

About the "true" rendition of colors, I think it's about the same with DSOs. While pictures may show similar colors, they may depend on many factors, such as atmospheric conditions, light pollution, camera gear, etc. And, of course, artistic choices in post-processing, especially if you use monochrome cameras (duh). Since these colors are false by nature or exaggerated at best, I don't really see the point in finding their exact values. It all comes down to aesthetics, in my humble opinion. I've never heard of a Moonblink Device. Do you have any link or documentation about that? Colors are beautiful anyway, with or without hallucinogens. ; ) |

Some curiosities detected while exploring the colorful Mineral Moon photographs (these curiosities are only a few of many!): the yellow appearance of the central peak of crater Bullialdus. The yellow rim of crater Theophilus. The yellow colored northwestern "quarter" of crater Copernicus. The (of course) VERY yellow/orange colored Aristarchus Plateau (also known as Wood's Spot). The very sharp-edged contrast of the yellowish Mare Serenitatis and the bluish Mare Tranquillitatis. The orange-ish coloration of the (what I call) Lassell C isle, which was also observed from orbit during the mission of Apollo 16 in 1972, and many more curiosities (to fill a whole catalogue!). Another thing I often think about: - Wet rocks look much more colorful than dry rocks. The same with pebbles, cobbles, and boulders. Now, what if the rocks from the moon (from the Apollo program) were put in buckets full of water? How would these rocks look like? Imagine the moon with atmosphere and clouds, and... rain (a wet and much more colorful moon!). Further thinking... (off topic): If an Apollo astronaut went out and step'd off the LM with a bucket of water (after slowly depressurizing the interior of the LM's Ascent Stage), how would the water "behave" once it was poured onto the lunar surface? Immediately freezing to ice in the shadow of the LM? Immediately "vapourizing" in the sun's extreme heat? Or... just the same as on Earth? (a fluid substance). |

| Looks like pretty tough place to live. I imagine the water would boil at much lower temperatures than here on earth in that low pressure environment. But here's your weather report so I guess it would depend on when and where on the moon the bucket of water was dumped out. https://science.nasa.gov/moon/weather-on-the-moon/ |
