I’ve seen most of the trees (at least in Canada) change color in autumn to an orangey, I’ve heard it has to do with better absorption of sunlight waves that change during this time of the year.
But why they begin to change from top to bottom? I would think the inner ones or lowest ones would change first since they have less access to sunlight than the top ones.

Different trees do this differently. The birches outside my house get random yellow streaks that add up with time. Being exposed to a low temperature seems to kickstart the process. If it has to do with light and shadow when it comes to maples, it could be that being cold while being exposed to sunlight starts the process earlier.
