Class GeCssColorUtil

Colour gradients for heatmaps and conditional formatting – returns CSS colours like rgb(244, 114, 182).

Example

const gradient = new ThreeColorGradientArg(
  0, new ColorRgb(255, 255, 255),        // min → white
  50, new ColorRgb(244, 114, 182),       // middle → pink
  100, new ColorRgb(79, 70, 229));       // max → indigo

class HeatmapModel extends AreaModelArrayOfArrays<number> {
  override getCustomStyleAt(rowIndex: number, columnIndex: number) {
    const value = Number(this.getValueAt(rowIndex, columnIndex));
    return { "background-color": GeCssColorUtil.getThreeColorGradientRGB(value, gradient) };
  }
