How does Warcraft choose rainy weather?

Can I call dota? Just type-it's raining.

If you want to change the color of the river, you can-the water is random. If you want a specific color, you can change it yourself.

But some pink, pink and purple are not displayed. I only tried red and green. You can continue to choose colors at random until the color you want appears. The weather is the same, but randomness is not recommended. He will change it from time to time. Some things like fog and snow are more expensive. Graphics cards will have some cards, so I only recommend rain and moonlight, and I use them more.

I hope this helps.
