Wow 12 cones that is 24 distinct hues. With 12 of them being completely different from each other and the other 12 being a mix of 2 of the main 12. Those original 12 will also be the color of the pigment bound to the opsin protein. This why each one reacts the wavelengths of light they do. That is just impossible to imagine with our limited 3 cone color perception. Though there probably isn’t much of a difference since the range of visible light is close to the same. We can assume this because of the rare tetrachromat humans, humans with 4 cones; who see the same as trichromat perception with a little more intensity on the blue to violet hues.
Question. Alexanderite is green during the day or regular light, while it is red at night. So isn’t Alexanderite green under warm light and red in cooler or dim light?
Green in sunlight, red in incandescent light, I.e. candle light or a dim light 💡
Glad to see that you also know the rarest gemstones

Ah, at last! Someone showed the chart that proves dogs don't see in grayscale. They are partially colourblind, but not completely unable to see all colour, the way some people assume.
As for mantis shrimp, I imagine that infrared might look like a glowing brownish-black red. So, no matter what colour of visible light something is, it might look like it has a dark reddish sheen, or even halo around it. And I imagine that ultraviolet might look like a pale lavender that also glows. Maybe. That's a really interesting question. (What I really wish I knew is what a mantis shrimp would see when looking at alexandrite.)
Can you make a video about Amber and pearls?
