I have a back and forth that I want to turn into a simple switch. So I know there are 3 sons, 2 of the same color. I isolate 1 and gather the second with the one of different color. My question is: where should I connect these two wires and where do I connect the blue and red wires coming from the new ceiling light?

One of the two switches will remain in place "for the decor", it is at the level of this switch that you must intervene.
When you take the switch out of its housing, you see two sons of the same color and one third of different color. Connect one of the two wires of the same color with the third, make sure to isolate the remaining wire. The second switch will remain operational without changes.
