The story of the word

A hybrid: ἕξ is Greek and decimal is Latin, from decem. The consistent form would be sexadecimal, and early computing did use it, but IBM is reported to have preferred hexadecimal on grounds of decorum while the System/360 documentation was being written in the early 1960s. Whatever the reason, the mongrel won, and every colour code on the web is written in it.
