Romain Guy did not disappoint with his presentation on color at I/O. Color is so complicated that there’s no way to give a succinct introduction to it on Android in 40 minutes, but Romain did about as well as you possibly can.
I would say this is an intermediate level presentation, but if you're interested in learning about color for the first time it will probably feel like an advanced one. Don't worry about all the concepts you don't understand yet. I knew basically nothing two years ago before learning all the material in this talk. Even though color is a massive topic, the individual concepts are relatively easy to grasp. Give it a shot, and you can definitely learn all of the major points over time.
