What does the color sky blue mean?
this color mean funny, creative, and a thinker outside of the box
As you may know, when you mix the colors yellow and green, you get the color blue. The yellow from the sun reflects off of the green ground, making the sky look blue. At night, when there is no sun, you see that the sky isn't blue anymore. This is actually what the sky looks like all the time. The blue color is just an optical illusion. It is quite amazing though.
