Why is it so hard to accurately read resistor values on resistors.
You ask a question that is essentially impossible to answer since you give no clue as to what you mean by it being so had to accurately read resistor values.Why is it so hard to accurately read resistor values on resistors.
The numbers are off by one -it starts with black being zero.I have a bit of difficulty reading color codes too, but mostly because of my true color perception issues.
1 Black; 2 Brown; 3 Red; 4 Orange; 5 Yellow; 6 Green; 7 Blue; 8 Violet; 9 Grey; 0 White.

OOPS! WOW! Really messed that one up. Good catch. Yes, and thank you for the clarification. I knew black was zero. Don't know how I missed that so easily. Gotta start reading my own posts a little more closely.The numbers are off by one -it starts with black being zero.
Same here.In high school one summer session the technician in our TV studio made color code flash cards for me and it worked beautifully. Still, more than 50 years later when I see a color coded resistor I see the value, not the colors. Not only was he a good teacher, but also a really good technician.
It always amazes me how few references on the resistor color code ever mention the fact that the order of the central part of it was chosen to be the same as the rainbow. That gives you the central six. The other four, two at each end, are simply the extreme of the neutral colors -- black and brown at one end and gray and white at the other. I can't count the number of students that couldn't remember what color came after orange or after green but had no problem telling you instantly the order of the colors in the rainbow.Hello,
@gramps , there are many of those lists:

Yours is a bit offensive.
