I suspect there's a lot of truth in this.

This reminds me of going for an interview at Durham University in the early 80s. A professor in the physics department proudly showed me a prototype blue LED that they had developed. It was indeed quite a novelty at that time.

Ah, yes - a quick search confirms there was research in this area going on at the time: https://iopscience.iop.org/article/10.1088/0022-3727/16/6/02...

Undoubtedly I agree with both of you. Unfortunately, since the introduction of blue LEDs little thought has been given to the way people react to them. From my experience, they seem to raise the most criticism of all colored indicators.
