Hola, Samuel.

Por vs. para gets a little complicated at times. There are general rules, and then there are "set phrases" like "por la mañana" "por la tarde" "por la noche"

Here is a link to the teaching offered by SpanishDict. It will help you to get a grasp on why "por" is used in this sentence.

Answer 3

¿Dónde empiezo? Where do I start?

¿Por dónde empiezo? Empiezo por la roja. Where do I start? Or what do I start with? Or what do I start by? (Sounds weird) Or ...... I start with the red one. I start by the red one. I start through the red one.

Yo empiezo por la roja Is the same or almost the same as Yo empiezo con la roja.

Very i nteresting question Never thought about it.
