App/feature request: redshift

I'm interested in an app or a setting that adjusts the colour temperature of the screen similar to what Redshift and f.lux do on computers. I think it would be useful as an app if it would have a cover which would allow to switch on/off the colour temperature adjusting, or as a feature if you could easily enable/disable it in the settings.

I'm sure many other people are also avid users of Redshift or f.lux (or alternatives) and would agree this would be a nice thing to have. I don't know if this kind of app is possible yet or at all, but please consider the idea.

May be we talk to Bojan Komljenović(@knobtviker) he developed similar for N9, might we a small donation he can do it for Sailfish OS as well?

For reference, here is also a question asked to the author of Redshift about Wayland support (which is what Sailfish uses). It's a year old though, so I don't know if and how the situation has changed by now (maybe not that much considering Sailfish doesn't use the latest Wayland yet).

Who would ask Bojan? What was the name of the app? Maybe we can look at the source and port it to Sailfish OS? Also, here's an interesting discussion: https://github.com/jonls/redshift/issues/5

Is it on Sailfish roadmap or not?

I would absolutely love an app like Redshift; so many other Jolla users would benefit from an app like this too.

I use such functionality on all of my other devices and so it's extremely jarring to go from a nice colour shifted tablet or laptop to the Jolla in the evening.

I would suggest also raising this on talk.maemo.org for the attention of some Sailfish OS devs.

I just read this. It is for FirefoxOS but I wonder if the same technic could be applied to Sailfish Theme component (see now-sadly-offline-SDK for further details).

I'm pretty sure it's doable by connecting the light sensor (don't know if dev can access it, but I hope so) to a bit of maths (to compute the colors filters).

From what I heard, the problem is basically Wayland doesn't have colormanagement yet, and therefore you can't apply what you call filters. Anyone, more technically inclined can answer? The displays blue keeps burning a hole in my eyes. ;-)

I currently use the native app Tint Overlay. It is not available in the store, you must download the .rpm file. Link: https://openrepos.net/content/coderus/tint-overlay

@Soy works great for me, at night decrease blue 0, increase red 10, increase alpha 10, gives good night vision.

Although it's better than nothing, it's not a true blue-light filter app. Even with Red and Alpha turned up, some visual areas (soft keys, text cursor) are not filtered and show through.
