Three.js setHSL（）设置了意外的颜色

Question

  

setHSL（h，s，l）-在提供的HSL值上设置此颜色的值。取值范围是0到1。

为什么我尝试material.color.setHSL( 0.5, 1, 0.5 )时会发青？我希望选色器显示为黄色

let camera, scene, renderer, material;

init();

function init() {

    camera = new THREE.PerspectiveCamera( 70, window.innerWidth / window.innerHeight, 0.01, 10 );
    camera.position.z = 1;

    scene = new THREE.Scene();

    const geometry = new THREE.PlaneGeometry();
    material = new THREE.MeshBasicMaterial( { color: 0xffffff } );
		material.color.setHSL( 0.5, 1, 0.5 );
    
    const mesh = new THREE.Mesh( geometry, material );
    scene.add( mesh );

    renderer = new THREE.WebGLRenderer( { antialias: true } );
    renderer.setSize( window.innerWidth, window.innerHeight );
    document.body.appendChild( renderer.domElement );
    renderer.render( scene, camera );
}

body {
	  margin: 0;
}

拾色器从0到360。 setHSL从0到1。

如果您希望色相为360，则将50/360设置为0.1388888888888889。

setHSL（0.1388888888888889，1，0.5）是黄色的。

let camera, scene, renderer, material;

init();

function init() {

    camera = new THREE.PerspectiveCamera( 70, window.innerWidth / window.innerHeight, 0.01, 10 );
    camera.position.z = 1;

    scene = new THREE.Scene();

    const geometry = new THREE.PlaneGeometry();
    material = new THREE.MeshBasicMaterial( { color: 0xffffff } );
		material.color.setHSL( 0.1388888888888889, 1, 0.5 );
    
    const mesh = new THREE.Mesh( geometry, material );
    scene.add( mesh );

    renderer = new THREE.WebGLRenderer( { antialias: true } );
    renderer.setSize( window.innerWidth, window.innerHeight );
    document.body.appendChild( renderer.domElement );
    renderer.render( scene, camera );
}

body {
	  margin: 0;
}
