How to Change Font Color of Swimlane Header in React Diagram?

Header was the primary element for swimlanes. The header property of swimlane allows you to define its textual description and to customize its appearance in React Diagram .
To customize the font color of the swimlane header, you can use the color property within the style property within the swimlane header annotation. This allows greater flexibility in designing your diagrams.

Refer to the below code snippet for customization of font color in swimlane header

header: {
         annotation: {
           content: 'SALES PROCESS FLOW CHART',
           //update font color for swimlane header
           style: { fill: 'black', color: 'yellow' },
         },
       }, 

The below code example shows how to customize the font color of swimlane header at run time using color picker when the swimlane is selected

let node = [
 {
   shape: {
     type: 'SwimLane',
     orientation: 'Horizontal',
     // customize the swimlane header
     header: {
       annotation: {
         content: 'SALES PROCESS FLOW CHART',
         //update font color for swimlane header
         style: { fill: 'black', color: 'yellow' },
       },
     },
     lanes: [
       {
         id: 'stackCanvas1',
         height: 100,
       },
     ],
     phases: [
       {
         id: 'phase1',
         offset: 170,
         header: { annotation: { content: 'Phase' } },
       },
     ],
     phaseSize: 20,
   },
   offsetX: 300,
   offsetY: 200,
   height: 200,
   width: 350,
 },
];
let diagramInstance;
// initialize Diagram component
function App() {
 //update font color for swimlane header at run time using color picker 
 const fontColor = () => {
 if(diagramInstance.selectedItems.nodes[0] && diagramInstance.selectedItems.nodes[0].shape.type == "SwimLane")
 {
   let currentColor = document.getElementById('fontColor').value;
   diagramInstance.selectedItems.nodes[0].shape.header.annotation.style.color = currentColor;
   diagramInstance.dataBind();
 }
 };
 return (
   <div>
     <input type="color" id="fontColor" onChange={fontColor} />
     <label>Change header color</label>
     <DiagramComponent
       id="container"
       ref={(diagram) => (diagramInstance = diagram)}
       width={'100%'}
       height={'600px'}
       nodes={node}
     />
   </div>
 );
}
