My work LCD monitor has four settings for Color:

  • warm (5000K)
  • standard (6500K)
  • cool (9300K)
  • custom (each of the RGB values can be chosen separately)

What is the setting that could reduce at most blue light? I mean: changing color temperature would effectively affect the amount of blue light emitted, or it's just a graphic setting?

Or it's changed somewhere else on the monitor? Note that the monitor doesn't have a Blue Filter on/off option, otherwise I'd already have set it.

I'm not interested in software solutions - such as f.lux - because I am not allowed to install them.

Both.

It does affect the amount of blue light emitted. It is just a graphic setting.

All colors are made by mixing light of three colors: red, green and blue, in appropriate amounts. Reducing amount of blue light = making the color less blue. It's literally the same thing. If it appears less blue, then less blue light is emitted.

Setting the temperature to "warm" - or in other words, the lowest Kelvin) will give you the yellowest (reddest, actually, but it will look yellow) - and thus least blue setting.

6500 is equivalent to a "white looking" daylight LED bulb. 5000 is, from memory, equivalent to the yellow ones which look like the old incandescent bulbs.

Are you aware you can get glasses which remove the blue component of the light arround you? (gamers use them)
