Stacked Bar colors

In this bar chart

I would like to select my own colors for the lowest bars. I know I can used the color property but I don’t want the same color for each bar. I want the exact same look but I want to be able to pick the colors myself.

Solved. I just used getIndexById and used the index to select a color. This works fine.
