@reina3 These color effects are not on the "planckian locus" meaning there is no CCT that matches them exactly - this one is very close to 6400K but not really! We should allow scheduling these in a future version.
I was wondering if f.lux has any plans of developing Sunglasses with or without adjustable color/tint/...etc ?
The same for Dayglasses - for more general use. And Nightglasses - for driving, to reduce the brightness of today's overly bright headlights.
If you have never thought about that, so maybe it could be an idea. I think many many people are developing various eye problems due to large screens of TVs and computers, and blue light they emit.
@Yemafu the big reason to like TUV certification is that it ensures a low-flicker display, which is really helpful.
For blue light, this standard is not very effective, as it's a super tiny change in blue light, usually below 10%. You'd be better off with something that dims to a comfortable level, or adjusting your desk and the glare around it.
