HarmonyOS image图标怎么变成其他的颜色

import image from "@kit.ImageKit"; 
import effectKit from "@kit.ArkGraphics2D"; 
const color = new ArrayBuffer(96); 
let opts = { editable: true, pixelFormat: 3, size: { height: 4, width: 6 } }; 
image.createPixelMap(color, opts).then((pixelMap) => { 
  let bright = 1; 
  let headFilter = effectKit.createEffect(pixelMap); 
  if (headFilter != null) { 
    headFilter.blur(bright); 
  } 
})
