Famine: Why is the screen so dark that you can't see it clearly day and night?

This is normal. The darker the weather (not far from the rain), the darker the color. The hue of summer is the color when it is about to rain. Generally speaking, the color of summer is most affected by the gloomy weather, winter is least affected by the gloomy weather, and spring and autumn are moderately affected by the gloomy weather.

You can open two summer stalls, one for no rain and the other for the heaviest rain. Compare it.
