What is the relevant spec for colors here? Is there some ISO or whatever for signal lights on equipment defining it?

- fxtentacle 5y agoParent comment probably meant "colorimeter" which will measure colors in either spectral distribution or XYZ color space. So you could say something like RAL color # 123 +- 5% in XYZ space. Or you can just specify: That color needs to be closer to RAL #123 than to any other RAL number, so then you'd also have an implicit definition of the valid color range.
- detaro 5y agoWhat the "something like" is exactly and where it came from is kind of my question.
- jwandborg 5y agoIt might be regulatory concerns, maybe they hadn't licensed that particular wavelength of orange for local broadcasting purposes, or EMI concerns with regards to the the off-white spectrum, at least if I let my thoughts run without moderation.
- foobiekr 5y agoNo, this really was just ethernet interface front panel LEDs. The customer viewed this as indicative of poor quality control.
- foobiekr 5y agoWe publish the relevant wavelength on the data sheets. This is for interface LEDs on a network device. This was one batch of a few hundred chassis, and they ended up being _just_ _slightly_ more yellow than the rest. Back they came.
