@ SQB: That is really the main problem. And you hace another estimation than other. Your screens all look worse than the standard in my opinion. It has much to do with the monitor and its settings. So it is hard to understand your efforts, because they are all tinted drastically. The approach of jupp is quite fine to me.
I think, the problem with monitors is important here. On my oled display or retina, it looks too much colour and the sunset is too overwhelming to me (looks like the sunsets in gta4, which is horribly overdone). What pabel do you have? TN or an ips or another? Did you tweak your monitor before tweaking the game? It looks like you have another view than me, e.g.
A little weird. Overall we already claimed the colours of clod some time ago and even olegs initial settings were too colourful. And changing settings this way could effect new scenarios like BoM badly. So I think I will try an easy implementation like jupps and will go back standard, if not suitable for bom later on.
