Following a wider conversation regarding colors, I would suggest to introduce borders between adjacent elements in order to improve readability and to make it simpler to tell apart visual shapes in charts.
We already do this in partition charts for examples (pies, donuts, treemaps...) but we don't do it in stacked barcharts, it would be great to evaluate the feasibility of this and the potential consequences
