Sankey-diagram PowerBI custom visual with color nodes and ordering

The sankey diagram of PowerBI has many possibilities but as you can read on the github site there are some important limitations. The first is that it is not possible to color the nodes. In addition, it is also not possible to change the order of the nodes (both source and destination).

Attached is an example PowerBI file in which a sankey is displayed. In this file is indicated which colors the nodes should have and what the order of the nodes should be.

The best solution is of course to use PowerBI to indicate the colors as in this example with the links. But probably it is easier to indicate the colors of the nodes (names) in the code itself with a hard value this would also be a nice alternative. Same holds for the ordering of the nodes

I looked at the colorscale function of d3 to link it to fillcolor. But I got an error message that the string values cannot be linked to colorscale.

The Github page with the code can be found here: https://github.com/microsoft/powerbi-visuals-sankey

I think this line of code should change:

nodeFillColor = this.colorHelper.isHighContrast ? this.colorHelper.getThemeColor() : this.colorPalette.getColor(index.toString()).value;
console.log(nodeFillColor);
nodeStrokeColor = this.colorHelper.getHighContrastColor("foreground", nodeFillColor);

The colors are now based on a theme color. Hopefully it is possible to link the nodes (name) to a color instead of a theme.

Hopefully you can help me and other users of the Sankey.
