I second this. Is there any possible way to do this? I would be happy to help in development or testing of this feature if someone knows how to do it

We are only telling the macOS to change modes, which I'd assume is like clicking on the system preference.

Have you also reported this to WhatsApp? (because they're more likely to be able to fix it...)

@kushclarke said in enable custom color-modes without relation to actual time (Reader Mode):

Have you got the solution? If so, then please tell me the best way. Check out this guide now.

What about this?

What was the color temperature in f.lux?

You see, I think it was due to the color temperature being so warm and red that it actually made the highlighting become impossible to see due to the color of the highlighting mixed with the color temperature from f.lux. I think that's why you could see the highlighting after sunrise. After all, after sunrise, the color temperature by default goes back to 6500K.

Try this: open a document that has highlighting. Then, open the f.lux window and slowly adjust the color temperature until it gets as warm and as red as you can possibly get it. I think you'll find that as you make the color temperature warmer, the highlighting becomes less and less visible and finally completely invisible.

Thanks @crazydef! That did it for now :)

any idea when this might be fixed? It's pretty annoying having to disable flux twice at different times just to get my screen into full day mode in the morning

This can happen if you use Darkroom mode. If f.lux doesn't fix it for you (it should) you can toggle it in System Preferences > Accessibility >Display >Use Grayscale

Thanks!!
