public 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.

using UnityEngine;

public class Example : MonoBehaviour { Light lt;

void Start() { lt = GetComponent<Light>(); }

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

Another example:

using UnityEngine;

public class Example : MonoBehaviour { // Interpolate light color between two colors back and forth float duration = 1.0f; Color color0 = Color.red; Color color1 = Color.blue;

Light lt;

void Start() { lt = GetComponent<Light>(); }

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