# RGB24

> Three channel (RGB) texture format, 8-bits unsigned integer per channel.

## Definition

* **Type:** Field
* **Namespace:** [UnityEngine](/engine/6000.7/script-reference/unityengine.md)
* **Assembly:** UnityEngine.CoreModule

```csharp
RGB24 = 3
```

### Remarks

Note that there are almost no GPUs that support this format natively, so at texture load time it is converted into an [TextureFormat.RGBA32](/engine/6000.7/script-reference/unityengine/textureformat/rgba32.md) format. RGB24 is thus only useful for some game build size savings.
