> LVCS...is available in industry-standard light blue

Is this tongue-in-cheek, or is there a reason manufacturers care about the color?

In various industries, colors are used to differentiate between various voltages so it's obvious whether you're working with high voltage, low voltage, etc. so you can determine the necessary precautions for whatever you're dealing with (and some will also make the connectors incompatible so you can't accidentally join high and low voltage sets of wiring). I'm not super familiar with the automotive side, but I believe they use orange for high voltage and light blue for 48v.

They tend to color-code connectors in vehicles by voltage for safety reasons.

Light blue is used for 48V.

Meanwhile 12V connectors turn up in a wide variety of grey, where different colors might just mean the connector is keyed differently.

Mid voltage (~48-60) uses light blue.

Ideally you should be able to differentiate high voltage (orange, iirc), safety (yellow), mid voltage, and everything else.
