History of Resistor Color Band Code

[Hi-Fi-Mogul]

I am very curious about the origins of just about
anything.

Today, it popped into consciousness: where did the resistor
color code come from ?

This link supplied some interesting info. I could not find a
complete Radio Physics Course book online to dig in
further.

That was a nice reference for the ordering of the colors. It's funny that they can still mark values on components that are not too much bigger than the punctuation marks on this page, yet they had to use paint dots on components the diameter of a cigarette back then.
