The color coded rings on resistors is a mightily bad idea, at least as implemented on resistors.
I'm not that colorblind, I see traffic lights, fruits between leaves and other things others have problems with, basically everything except resistor rings and distant lighthouse colors (yes, the colors on a map make sense, but trying to decode them IRL is as hard as resistor codes.)
The worst thing is resistors with weird background colors for the color bands. I can usually figure out beige resistors, but the blue ones? no chance of getting those right.
Yep. Just do it on the cable, heat shrink some wrapper around it and make it extremely obvious on the box. Try walking Grandma through what cable and charging brick to use over the phone when she calls you while she's at walmart
I recall coming across the color guide for the various features, like blue for USB3, and red for… power delivery, maybe?
But then one day I was on AliExpress or Alibaba or something and seeing that you could just buy cables from some manufacturer with whatever color you wanted. And I lost faith in the reliability of color id for cables.
Right, but it’s still easier to explain “either green or blue”, and the colors are in rainbow order for a reason.
It’s not just for grandma, most everyone would have an easier time remembering the “working” or “fast” colors than having to think about Gbps or watts, myself included.
