I wonder if you could cheat natural daylight by using big RGB LED area lights emitting at just the right amount of Kelvin.

The aural equivalent (https://rainymood.com/) certainly works for me.

To make it seem like sunlight you have to simulate Rayleigh scattering. I remember seeing a company that was making artificial skylights that did this, but can't seem to find it anymore.

It's not only the Kelvins, but the intensity also.

Natural light is around 100K lux. That is crazily expensive to generate.

As a counterpoint, I wouldn't want to work in daylight / outside; still need to be able to view a monitor.

(I sit next to a window atm. It's a bit annoying when the sun shows up after lunch)

10,000 != 100,000

Yeah, I wasn't really talking about the lux level, but rather about "cheating natural daylight". Unless your office window is getting direct mid-day sun (so it's.. a skylight?) you aren't getting close to 100k lux.
