I'm going to perhaps surprise you and recommend that you ask this at /r/linguistics. Whether people can experience things they don't have the language to describe is a matter of debate in their discipline, often referred to under the Sapir-whorf hypothesis. You may also want to go over to the blog language log and see what they have to say about it.

Edit: and color words, especially blue and orange, are a huge part of the Sapir-Whorf discussion.

To clarify something that you may see discussed if you bring this question to r/linguistics-the issue within linguistics has to do with how the color spectrum is divided up and how blue is partitioned out from green, not with actually seeing what we consider "blue". For example, if you put two shades of very light and extremely dark green next to each other it is possible to categorize them as different colors or alternately to categorize pink , purple, and red as lighter and darker shades of the same color. How these categorizations affect our color perception is a complicated question, but certainly we know that many ancient cultures could perceive blue and blue colors even if they didn't have a distinct word for it-for starters, it was used extensively as a pigment in painting and enamel work

hi.. just ran across this post. There have actually been several discussion on colour perception & words in this sub; check this one out, which includes a bunch o' links

• I've been reading that, before the Egyptians in 2500 BC, people from older cultures had no word for the color blue. Is the ability to see blue a somewhat new trait in humans?

There is nothing in the first article that says that any culture did not identify the color blue. It specifically says there were three great types of blue in ancient times: Egyptian, meso american and Chinese. Nothing in the article says anything about blue and modern times.

Why cite an article like that?
