2 problems here: color and intensity. 1. Color. Blue is more rare in nature than other colors and it has a known association with daylight that is disturbing for sleep. Why not something more neutral like orange (not red, not green)? 2. Intensity. I think the manufacturers don't even think about this. For indoor use, full brightness makes no sese, but bad UX is the default choice for most, what TV manufacturer pays attention at their user experience with the standby led? I guess they never think about it.

> Blue is more rare in nature than other colors Since the sky and the ocean are blue, that suggests a majority of visual field in nature contains blue in most cases.

  Daylight sky, with emphasis on daylight, and ocean blue only for people living next to a large body of water. Objects in nature are rarely blue. At night, nothing is blue, most of our history the only color at night is the orange-reddish of the camp fire (and yes, 100 years of light bulbs don't replace 50,000 years of conditioning of camp fires).

  Yes but not the deep intense blue from most standby LEDs.

    Same could be said of green or red though. I think it’s time to stop repeating this just-so story.

      Hmm no but the intense deep blue is not good for the eyes and can even damage the retina at intensity. Green or red don't have this issue. It also has a noticeably different refractory index which is why red directly beside blue looks 'off'.

I think the blue is still considered "cool" perhaps precisely because it's rare and it was the last LED colour to be available cheaply. It seems to be a rather persistent trend, though. In the UK a blue light on an electric kettle has been standard for the past 15 years at this point. Red/orange and green seem deeply uncool as they are associated with neons and old LEDs that have been available basically forever at this point.

  Fully agree with the reason behind blue LEDs, but it does not make it acceptable for end users. I would prefer orange any time, green and yellow have too often a status meaning (good/bad), while orange does not and I think it is more neutral.
