Change color in Line2

Questions
1

hi,
I draw lines with “Line2”

I try change colors and try again and again…
but, it always same result black line;

how can i change colors in Line2?
please save me :fearful:

this is my create and input color script

const positions = [];

      //  const colors = [];
      //  const color = new THREE.Color(Math.random() * 1, Math.random() * 1, Math.random() * 1);
       var target = new THREE.Vector3(); // create once an reuse it
      //  ObjectMesh.getWorldPosition( target );
      //  three.scene.updateMatrixWorld(true);
       positions.push(0, 0, 0);
       positions.push(ObjectMesh.position.x, ObjectMesh.position.y, ObjectMesh.position.z);

      //  var point = new THREE.Vector3();
      //  point.setFromMatrixPosition( ObjectMesh.matrixWorld );

      //  colors.push(color.r, color.g, color.b);

       const geometry = new LineGeometry();
       geometry.setPositions( positions );

       geometry.setColors( colors );
       geometry.setColors( 1,0,0 );


       let matLine = new LineMaterial( {
        color: 0xffffff,
        linewidth: 0.003, // in pixels
        vertexColors: true,
        //resolution:  // to be set by renderer, eventually
        dashed: true
      })

      let _line = new Line2( geometry, matLine );
      _line.computeLineDistances();
      _line.scale.set( 1, 1, 1 );

      return _line;
