I don't mind things going off topic as long as it is interesting and informative like your post. If it goes off far enough and doesn't come back is where I will create a new thread.
(since @Grendal has allowed this brief excursion, and it's before trading hours)
This would seem to contradict that: Egyptian blue - Wikipedia :
He asserts "Blue" isn't mentioned in the Bible... it is in Exodus, which is understood to be written 3500+ years ago... hundreds of years before Homer's writings he referred to as making Gladstone curious about the issue...
Not sure where this guy is getting his info...

I wouldn't worry about the minutiae. The interesting bit for me is that the written word evolved over time to be more and more specific about colors. Why come up with a color for blue when you don't need to communicate that to anyone? It's only when the distinction between sky blue and grass green is somehow important that you come up with words to distinguish between them. People may just have said "grass green" and "sky green" to get the point across.
To illustrate differences in perceptions of color, here's a favorite comedy sketch of mine from the classic "Mr. Blandings Builds His Dream House".
It humorously underscores that women are more perceptive of color because it's more important to them and what they do. Then there's the fact that 12% of women are hyper-aware of color. I wonder if it's a survival trait. Is spotting a distinct shade in your child's skin helpful in understanding their health? How about a distinct shade in food being prepared to spot spoilage and such?
Sure... I get the variances in, and evolution of, language part. It's why some cultures have 20 words for snow and others have none...
But the implication that human beings were unable to see blue, rather than just not coming up with a name for it is what that video is claiming, based on assertions that are pretty trivially shown to be incorrect or questionable.
Do you see dollar bill green, tree green and grass green as distinct colors? Side by side, sure, you understand that they contrast. But when asked to draw each of those objects from memory, you'll grab the same green crayon just like the rest of us. That's because you and I actually only have one place in our brain for green, regardless of the shade. That's the sort of phenomenon that the Greeks may have experienced. Sky blue was just another shade of green. Asked to draw a sky, they might also grab a green crayon. It won't look as good as a true artist who would grab a different shade of green (what we call blue), but it'll make sense to them that the sky is a sky.
Yeah, I'm sure that explains part of it.... not to mention that there are more green-sensitive cones in our retinas, which matches the fact that green makes up the majority of white light... so nearby on the spectrum "being a shade of green" I'd argue is a plausible explanation....
Just over 21 hours to go until the landing attempt tomorrow.
Landing time is now 18:24 EST, 17:24 CST, 16:24 MST, 15:24 PST.
The Launch Pad's stream says that IM wanted to go one more orbit before landing.
