Interesting blog. It would be great if you can provide more details about it. Thank you.

Interesting thought... If you've ever paid attention to preColumbian art in the Americas, you'll notice that ALL the space is filled in. Faces, buildings, animals, etc., are all crowded together to fill up the entire surface of painting or sculpture. IOW, there's no sky. No ugly blue.

Makes me curious. Are there preColumbian art works which show river or sea scenes? And are they filled up the same way, to exclude the water?

I had never thought about this. I'm not versed in this at all, but the Maya things I've seen don't show the sky, do they?

One thing I didn't mention in the post is that the progression of naming (actual) colors is from low to high frequency. Perhaps that's important.
