What I want to see is someone go through and assign sRGB colors for each of the main LED types. It's surprisingly difficult. I've failed every time I've tried, in that what I come up with doing it by starting from the spectra (or a simple gaussian approximation) looks on screen nothing like the real LEDs. The greens (515-525nm) are particularly difficult.
I recognize that sRGB will never be able to do a perfect job, but it seems like it has to be possible to do decently well.
(What do I need this for? I design electronics. I use LEDs as indicators. I like to show the true color of the LED in my schematics and documentation, as best I can. And I try to never use the same color twice, in small and bespoke things, so there's less risk of indicator confusion, which means I've often got a lot of funny colors around.)
Very cool to see this on the front page - Don's "The Most Efficient LEDs!" site at https://donklipstein.com/led.html is a great resource, since it is very hard to come by reliable information on early commercial devices!
We used some of this data to trace progress in LED development for our recent Nature Energy paper on technology spillovers in solid-state lighting: https://doi.org/g9kcjd.
