00:00 Why is the sun yellow?

00:01 Because yes, normally it is white, the color that is composed of all the others.

00:05 So what happens?

00:06 Well, when its light reaches our atmosphere, the oxygen and nitrogen particles capture

00:10 and diffuse the blue light of the spectrum.

00:12 That's why the sky is blue, and the mixture of the remaining colors gives yellow.

00:16 But then why is it sometimes orange or red?

00:18 When the sun is in the horizon, its light must travel further to reach us,

00:22 which means that the shortest wavelengths disappear in our eyes,

00:25 and there is only a red or orange color left.
