Question about Ember 1200K color

podkall

I remember setting flux to Ember 1200K setting, and it was very red.

But now when I set flux to Ember 1200K the screen doesn't go red anymore,

It's not even orange it's almost as if it only removed most of the blue but doesn't add any red or orange..

When moving slider from 1900K to 1200K red things start to get darker.

Why?

Can you post f.lux options > driver info?

You can also try turning off "Use GPU for better quality with very warm colors" to see if this helps.

not using GPU gets rid of the very dark red, but the Ember color stays same

As for driver info, idk why that's important but:
