Red violet and purple are the opposite (complemtary) of lime green and yellow on the color wheel, but it would be impossible to find a larger pot with those colors. Hehe
They had a purple/gray one not long ago sell on FB auction. One of Walter Pall's that Jennifer Price was selling. They make them...or, speak with one for commission. But I think sliding into the blues could also work.
It didn't allow me to put in more so I put in colors that are easier to find. What do you have in mind?
It's a nursery plant. I cut some of the top off so I could fit it in my car. I'll keep it in a 21" rectangular colander pot or a plastic tub probably. I do have a mustard colored pot this big, Sorce. LOL
Something very dark, almost black.
This is out of instinct, I mind you. I know nothing of pots, as I said elsewhere...
Just my own aesthetics.
I believe it would contrast in a stunning way the golden leaves.
