What's the best way to color code this map ?

So you can color the bodies of water in blue

Then color the extent of the Shang Dynasty in a color of your choice as long as it is not blue

Then color the extent of the Zhou Dynasty in another color that is not blue and not the color you used for the Shang Dynasty

For the border of Modern China it would be very helpful to use a black marker to trace it .

I hope that this helped you out a lil
