@lzp0070007 可以使用colorMapping参数，键名为CSS颜色，键值为目标颜色。另外注意三波段渲染时的max值是否包含了nodata

type TIFFImageryProviderRenderOptions = {
  /** nodata value, default read from tiff meta */
  nodata?: number;
  /** Only valid for three band rendering, defaults to { 'black': 'transparent' } */
  colorMapping?: Record<string, string>;
  /** try to render multi band cog to RGB, priority 1 */
  convertToRGB?: boolean;
  /** priority 2 */
  multi?: MultiBandRenderOptions;
  /** priority 3 */
  single?: SingleBandRenderOptions;
  /** resample method, defaults to nearest */
  resampleMethod?: 'bilinear' | 'nearest';
}
