   I have the following chart options in my Angular application for a sankey 
chart:
   
       this.chartOptions = {
         color: ["#922752", "#ff9822", "#4390e1", "#53bcbc"],
         tooltip: {
           backgroundColor: "#ffffff",
           borderWidth: 1,
           formatter: `<b>{b}</b><br/>{c} ${this.unit}`,
           padding: 8,
           textStyle: { color: "#212529" },
           trigger: "item",
           triggerOn: "mousemove",
         },
         series: [
           {
             type: "sankey",
             left: 0,
             top: 0,
             bottom: 0,
             nodeWidth: 10,
             data: this.seriesData,
             draggable: false,
             label: {
               fontWeight: "bold",
               formatter: "{b}",
             },
             links: this.seriesLinks,
             focusNodeAdjacency: "allEdges",
             itemStyle: {
               borderWidth: 0,
             },
             lineStyle: {
               color: "source",
               curveness: 0.5,
             },
           },
         ],
       };
   
   This is the current result:
   
   [![sankey chart current][1]][1]
   
   But the goal is that on the first level each node should have another color 
and the levels underneath it (depth +1) should have the parent color but only 
with -10% color saturation.
   
   Example:
