Hello, I do like red and it is my favorite color.
Hello! Do you know why sunsets are red? It's due to Rayleigh scattering.
So that's what causes the color of red, the scattering?
I'm not actually sure. I can say, though, that red is next to orange at one end of the light spectrum.
Ok, then what color is after orange in the light spectrum?

Response: Ah yes. the color after orange is yellow.
