r - SunburstR: vector of colors

Question

I've been trying to change the colors in my sunburst plot using sunburstR. I df have 3 levels (level 1 to 3 from centre) and the size. I create the plot fine just using the sunburst(df) but I would like for the colors in level 2 and 3 to match the color in level 1 but using different shades.

I've tried defining colors and lebels as suggested here How to specify the colors and toggle labels for each category in R sunburst? but the best I get is:

I actually would like for subsets in level 2 and 3 to have the same level 1 (centre) color but different shades.

I hope you can help me. Thank you very much

It sounds like all you need to do is add the extra two transparency characters for the hex codes.

In R, these two extra characters fit on the end of the hex code. For example, #c994c7 is the root color and #c994c780 has 50% transparency.
