I can't, I'm colourblind. That's why I had to drop electronics and go into software. It was a hard requirement in the UK in the mid-90s when I needed to make a choice.
To be fair though...I haven't used a through hole resistor in a long time.
Once you get down below 0603 there are not even labels on most resistors.
Yeah I learned the color codes way earlier in to my training...but it is largely irrelevant nowadays.
Also, it isn't just brown/dark red. Gold band can look like brown at times. Causes issues on 5 band resistors where the multiplier is gold. [1]
I had someone in industry with a board they were testing techs with that had one of these snuck in. I was the only one to figure it out...took me 10min. Some of the long term techs never fixed it. (I suspect one of the assemblers did it on purpose because they all knew the answer when I found it).

What does not make sense is to have such brown vs dark red scheme in the first place.
