Scenic View at the School Window

A while ago when I'm in the school, I saw the sun like this even it's raining. I was astonished and I quickly took a photo of it. The color of it was really pure orange.
I didn't capture clear photo because it was covered by the pine trees. I think it took five minutes when it vanished.

Dear friends, what does it mean why it goes color orange? 😄 It looks like red but it's not. I don't know why, maybe because of my camera.
