. . . I wrote down what I thought the colors were and got the color codes correct based on what I saw . . .
This sounds like my brother-in-laws story - he claims he could distinguish all the colors of the wires themselves looking at them but the actually color blind test he failed to many of where you see a number in a sea of color circles.
the sea of circle is the one that I fail,
but the FAA just asked me to Identify a Solid Color of RED or GREEN.
that was easy for me, and I got my clearance to get flight training....
owned Piper PA-22-160 N1797 for many years.
sadly, a subsequent owner/borrower put it in the ground
According to the circles of dots, I can't even see colors at all but I definitely do not see things in shades of gray only. RGB (Red, Blue, Green) are my weakest colors. Green traffic lights look white to me but grass looks green.
Red LEDs not only appear dimmer to me that they do for others, they focus differently than other objects around me. Blue doesn't look as intense for me as it does for others.
There are times I can't tell if an LED is red or green. I had an ASUS MOBO that had an LED backlit logo that indicated if overclocking was on or off by display either red or green. I never could tell what color the display was. I had to go into the BIOS to make sure overclocking was disabled (sometimes, it turned itself on and the computer would start running hotter).
When I worked at Motorola and I got in a new batch of components, I would just take one across the hall to the incoming mechanical inspectors and ask them what the colors were, then I could just visually compare it to a sample of others in the batch before testing them. No one seemed to have a problem with that.
One of two things that drove me nuts lately was when making up, repairing, or modifying Ethernet cables since I often can't tell one pair from another. If I have both ends right in front of me, I can use my DVOM to sort them out. If the ends are separated, I have to guess which is which, then use a tester to see if I got it right (it often took several tries to get it right since the tester results were only pass or fail). Most of the time, I just use patch cables that are close enough to the length I need. What I should do is make an adapter I can plug one end of a cable into that has different resistors across each twisted pair, then use a DVOM to compare the resistances across the pairs on the other end but I haven't needed to make up cables often enough to be worth bothering.
The other is this *&^%$#@! machine that the DMV here uses to test vision. It shows blurred blurred characters inside the machine that have to be identified. Since the characters look like they are a mix of colors, the red focuses differently than others and makes them look even more blurred. I would like to meet the clowns who invented that machine and approved its use.
