    javascript - THREE.Color: Unknown color #002dff (warningerror) - Stack Overflow

    programmeradmin4浏览0评论

    I need to update the color after receiving the value from dat.GUI . But, this 

    var colored = new THREE.Color(value.replace("#","0x"));

    is throwing this warning "THREE.Color: Unknown color 0x002dff" and the 'colored' isn't updating.

    value = #002dff (at that time, it keeps on changing, user input)

    Edit: I know I can use this as "THREE.Color( #002dff )", but the color is changing at run time according to the user input from controls I've created using dat.GUI, so I won't be knowing the actual value that can be added to the code.

    PS: It was replace() which was causing the problem. It's solved.

    • wow just pass it like new THREE.Color("#fff000") or etc – Maciej Kozieja Commented Jun 7, 2017 at 11:11
    • Only if I could. I mentioned that the value is generating from dat.GUI . – Utkarsh Zaveri Commented Jun 7, 2017 at 11:19
    • What revision of Three.js do you use? In the latest revision (r85) it works totally fine. – prisoner849 Commented Jun 7, 2017 at 12:53
    • r84. And I doubt it'll work as dat.GUI returns string value and the color constructor requires Hex value. @Hellium just mentioned this in his ment. – Utkarsh Zaveri Commented Jun 7, 2017 at 13:01
    • Take a look at my answer and check its example, please. – prisoner849 Commented Jun 7, 2017 at 13:04

    Reset to default 14

    You have to give a hexadecimal number, not a string to the Color constructor. Try to call the parseInt function:

    var colorValue = parseInt ( value.replace("#","0x"), 16 );
var colored = new THREE.Color( colorValue );

    try this ((new THREE.color("#FF00FF")),.if you want to choose a favortie color for your program .check this link out http://www.rapidtables./web/color/RGB_Color.htm ,are got to the photoshop and their you can select the color and it shows the color code .

    THREE.Color() has the .setStyle() method.

    var obj;
var gui = new dat.GUI();
var props = {
    color: '#002dff'
};
var colorController = gui.addColor(props, 'color');
colorController.onChange(
    function(value){
    // unment this to see it's working
    //var colored = new THREE.Color(value);
    //console.log(colored);
    obj.material.color.setStyle(value);
  }
);

var sphere = new THREE.Mesh(new THREE.SphereGeometry(2, 32, 24), new THREE.MeshStandardMaterial());
sphere.material.color.setStyle("#002dff");
scene.add(sphere);
obj = sphere;

    jsfiddle example. three.js r85, dat.GUI 0.6.5

    PS Don't use new THREE.Color() to change an exisiting colour of a material, use setXXXXX() methods of THREE.Color()
