Am colour blind, need help identifying bands
EPAIII:
This conversation makes me wonder if there may be a need for some kind of color recognition device. Not just for resistors/inductors or other electronic devices, but more general. Perhaps something that could be built into a pair of glasses.
But then, perhaps that already exists. I don't have time to do that search.
NiHaoMike:
Place a sheet of white paper off to the side (and in view) so that the color balancing will work.

That does exist, it's called a color filter.

Yes, I am now starting to wonder if the second inductor could be 221 rather than 220 :-DD
(But it really looked identical to the first on the original picture, so I think they are the same).
ivaylo:
Just measure them. This system is ridiculous. I have the red/green deficiency too and always thought people with normal color vision just see stuff where I usually stumble. Thanks for this thread…
magic:
It's easier when you have the device in front of you and can compare it with other stuff on the board and try a better light.
In comparison, decoding markings from somebody's single small picture is like reading tea leaves.
