does anyone else find it weird how silver and gold are used in completely different ways for the multiplier and tolerance bands?
as a multiplier, gold is 0.1 and silver is 0.01, but as tolerances gold is 5% and silver is 10%
and then you also get brown 1% tolerance and red 2% tolerance which, at least those make sense. why isn't 5% green though

should probably just drop the color code anyway, it's not good if you're colorblind
i get that it's easy to mark with the machines manufacturers have but also like
colorblind people exist, and even still those colors fade with heat so you can almost never tell what resistance old power resistors were to replace them
and the body colors! different manufacturers use different body colors and it's very often hard to tell whether you have a (light blue) metal-film resistor or a (teal) inductor

how about we just start using the same coding for through-hole resistors as for surface-mount ones
maybe swap to a rectangular prism body instead of a cylindrical one, so that it's easier to print on, and then use the three-digit codes with numerals instead of colors
"102" for 1 kΩ is a lot more accessible and harder to mistake for something else than "brown black red"
you still need to learn the code but there have to be tradeoffs when things are so tiny
-F
and it's not exactly *difficult* to learn, certainly easier than the color code
just take all but the last digit and read that as a number, then multiply it by 10 to the power of the last digit
if it's less than 10 ohms, it'll just be written directly, with the letter R in place of a decimal point (R for Resistance, because a decimal point would be missed too easily at this size)
