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

JavaScripts

// 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:

JavaScripts

// 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)
