Confused on old wiring color conventions

I am helping my sister-in-law with some wiring in her 1970's vintage home. when I opening up the junction box I was confused by the wiring colors. The wires appear to be black and tan rather than black and white or black and red as I am used to in more modern homes.

Is this normal? Is the black still the hot?

Never assume black is hot. ALWAYS use a meter. Are you sure it is tan, not just fades wires.

My color vision is not the best so I had my wife look several times. Yes, it appears sort of tan. My guess is it faded from white, but I did not want to assume.

So, the color conventions were the same back in the '70s. Just wanted to check,

The tans are whites that have faded.
