Could be mistaken but I think my Mac already does this -- it has "true tone" and when I open the lid, my main external monitor changes color temperature.

I wonder if there's a way to scrape that data and then send it to Home Assistant for light control.

If only color calibration were that easy.

People should really get comfortable with the idea that color is relative, so choose whatever looks nice to you and stick with it. True Tone certainly isn’t scientific.

In this scenario, all that matters is that the instrument doesn’t try to change its white balance. You can actually calculate the spectral energy of the sky based on these color changes alone, and it doesn’t matter if you start at a white balance of fluorescent or incandescent.
