I have been in the electronics industry for more than 45 years now. Since the early 1960s. When I first began working on projects, I recall that resistors had a red color with opaque painted bands for color codes. Or they were rectangular with opaque painted dots on them. Capacitors, too.
Then the modern thin film resistor came along and the larger carbon resistors went away quickly. They were painted beige with semitransparent paint and were quite easy to read. The colors against the beige were very easy to interpret and you could select a resistor by color code alone. Unless there was a manufacturers' error in the batch, the resistance was what the bands said it was.
In the past couple of years, the manufacturers in China have decided to change the body color to a light blue. In their infinite wisdom, they have continued using the semitransparent paints for the color bands. Sadly, all of the colors are now unreadable. Each component selected needs to be measured to be absolutely certain that you have the correct part in your hands.
I thought perhaps I was going a bit color blind so I had myself tested. Old eyes. Fortunately, nothing was wrong with them. I am not color blind and even with the brightest light on my work bench, the colors are still questionable.
I can't wait for them to run out of blue paint.

It's all about that moment when metal that hasn't seen the light of day for generations frees itself from the soil and presents itself to me.
