Light.color

var color : Color

Description

The color of the light.

To modify the light intensity you change light's color luminance. Lights always add illumination, so a light with a black color is the same as no light at all. See Also: Light component

JavaScript

// Darken the light completely over a period of 2 seconds.
function Update () {
    light.color -= Color.white / 2.0 * Time.deltaTime;
}

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
    void Update() {
        light.color -= Color.white / 2.0F * Time.deltaTime;
    }
}

import UnityEngine
import System.Collections

class example(MonoBehaviour):

    def Update():
        light.color -= ((Color.white / 2.0F) * Time.deltaTime)

Another example:

JavaScript

// Interpolate light color between two colors back and forth
var duration : float = 1.0;
var color0 : Color = Color.red;
var color1 : Color = Color.blue;

function Update () {
    // set light color
    var t : float = Mathf.PingPong (Time.time, duration) / duration;
    light.color = Color.Lerp (color0, color1, t);
}

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
    public float duration = 1.0F;
    public Color color0 = Color.red;
    public Color color1 = Color.blue;
    void Update() {
        float t = Mathf.PingPong(Time.time, duration) / duration;
        light.color = Color.Lerp(color0, color1, t);
    }
}

import UnityEngine
import System.Collections

class example(MonoBehaviour):

    public duration as single = 1.0F

    public color0 as Color = Color.red

    public color1 as Color = Color.blue

    def Update():
        t as single = (Mathf.PingPong(Time.time, duration) / duration)
        light.color = Color.Lerp(color0, color1, t)
