Well, I can tell you didn't bother to read the article.
"The only ancient culture to develop a word for blue was the Egyptians — and as it happens, they were also the only culture that had a way to produce a blue dye."
It is also possible that early cultures didn't name colors until they had a way to reproduce them or there are ethno-centric cultural subtleties that we are missing.
And then this: "
The World Colour Survey, looking at 110 language systems for colour terms, found Berlin and Kay's hypothesis, first explored in
Basic Color Terms: Their Universality and Evolution (1969), that there is “the existence of universal constraints on cross-language color naming” and “the existence of a partially fixed evolutionary progression according to which languages gain color terms over time” to be true. By presenting a Munsell colour chip and asking respondents to map out boundaries for colour terminology, similar results were obtained for different languages, although there were some outliers. Berlin and Kay then charted a path through which most languages took for naming colours.
Light and
dark (beyond just mere black and white) were firstly distinguished, followed by the addition of
red, then
green or
yellow.
Blue is only a clear category of its own after the first five are established, after which
brown comes into its own.
Purple,
pink,
orange and
grey are the final additions."

This hypothesis is still being challenged in academic circles and has not been conclusively proved or disproved, but I thought it interesting enough to post here. This is the thread for outrageous theories afterall.
