I have zero emitters in my scene. Zero. Just sun/sky.

maybe you should try a different white point setting like D55 or D65.

Queck Whitepoint settings. switch them to the default settings, to test the interaction.

And Upload the file, more easier to find the prob ;)

Check if your sun is under the horizon line and has negative values for height position.
Normally the color should be purple if it is, but maybe its also the same problem here ;-)

How did you model the glass panes, and what material do they use ?

Be sure that the walls have a thickness too, to prevent light leaks. You could have posted this in you wip, since the issue is related to the scene.

That's the wierd part. It's the same scene I used in my other wip. It worked fine when I reverted to the original version.

@zomB : How would I check that?

Edit : Since indigo is physically accurate by design, im thinking it wouldn't matter if a bit of light leaked out, since the scene still had a lot to go on.. I mean, shouldn't indigo just be rendering what you see? For that matter, why is tonemapping even neccesary. Sorry, just a thought. :)

The problem is that what you see is also what you made :?

Let's share it with us somehow ;)

As I mentioned, fixed the problem by reverting to and old version. Still, I think it would be good for myself and others to know whats behind this issue.

That's not entirely correct.
The sky-colour more or less is gradient based
Deep-violet is the colour you get at midnight. Deep-yellow is at 3h after sunset.... Or something^^ (It's a very rough number, especially as I dunno, how far the sun goes down the horizon after 3h^^)
Simply don't use a time, where the sun isn't visible between the horizon and the zenith - anything beyond the horizon gives crazy unrealistic values, based on a continuing of the sky-time-gradient...
Btw, you can also design "never", which is if the sun is at 0 0 0 :)
