If you look out your window right now, you'll probably be able to see a tree of some sort out there somewhere. Depending on the time of year, it might be full of beautiful green leaves, or under the right conditions, you could be looking at a rainbow of autumn colors in front of you.

But do you know why a tree's leaves change colors? There is a lot of science that goes into this process, and the end result can vary drastically based on a number of factors.

We've looked into what causes leaves colors to change, and eventually fall to the ground (in most cases) but also what the science is behind these changes, and a few ways that you might be able to predict what colors you can expect to see this autumn.
