Please add feature to customize sunset hours

[shigaugi]

Hello
I'm a graphic designer and I use to work till 19:00 ~ 20:00
The sun sets here much earlier, so I need to see true colors while I work.

That's why It would be amazing to keep using your utility and be able to manually adjust when to "warm up" the screen colors (When I stop working...)

Please add this feature, it will make your utility so much more useful to folks like me who need to see true colors while sun has already set, but later on want to filter the blue light.

Thank you so much!
