I don’t suppose you happen to know Why the sky is blue?
It’s because the snow takes out the white. That leaves it clean.
For the trees and grass to take out the green, the pears and bananas start to mellow, and bit by bit they take out the yellow.
The sunsets, of course, take out the red and pour it into the ocean bed or behind the mountains in the west. You take all that out and the rest couldn’t be anything else but blue.
Look for yourself. You can see it’s true.
