I am unresolved about the pot colors so I am going back to finishing the leaves. My clever ideas for pots didn't work out when I made test samples. (That is the photo with red, yellow and blue swatches.) But after some time of mixing various things, I finally got the green-black I wanted for shading leaves. I circled it with pencil. What I like about it is subtle, but if you look closely, you can see three different colors in it. That should give added depth. Wish me luck!
