That is a nice plant. There are other bumpy hybrids which would fit the bill. "Vito" is another one. They don't get big. The strong colors are going to be muted or absent indoors, depending on the light. The more light you can provide, the better the colors will be.
Here are two seedling hybrids (siblings) with nice red highlights. They make bicolor flowers (red opening to yellow) on and off all year.
