Distribute colors in collaboration chart in order of segment size

Currently, the collaboration chart segments are colored in clockwise order. The color palette was chosen to have sequentially contrasting colors. However, the segments usually have varying sizes, which means that less important segments might end up getting contrasting colors, while the bigger chunks are hard to distinguish.

For this reason, I’d like to distribute the colors not in clockwise order, but from the biggest to the smallest segments. In this way, the biggest chunks, which are most important, would get contrasting colors.
