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.

	// 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

public class Example(MonoBehaviour):

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

Another example:

	// 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

public class Example(MonoBehaviour):

	public duration as float = 1.0F

	public color0 as Color = Color.red

	public color1 as Color = Color.blue

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