# color

> Specifies the color emitted by the light.

## Definition

* **Type:** Property
* **Namespace:** [UnityEngine](/engine/6000.6/script-reference/unityengine.md)
* **Assembly:** UnityEngine.CoreModule

```csharp
public Color color { get; set; }
```

### Remarks

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

For more information, refer to [Light component](/engine/6000.6/manual/lighting-overview/lighting-birp/class-light.md).

```csharp
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:

```csharp
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);
    }
}
```
