## DESCRIPTION

**This node specifies the color to use for subsequent shapes as an index into the current color table. This is used only for BASE\_COLOR** lighting (see **SoLightModel**) in color index mode. Color index mode may be enabled by the window in which rendering occurs.

Since color indices make sense only in the context of OpenGL rendering, this node implements only a method for the **SoGLRenderAction**.

## FIELDS

**SoMFInt32**	**index**\
 Color index.

## METHODS

	**SoColorIndex()**\
 Creates a color index node with default settings.

**static SoType**	**getClassTypeId()**\
 Returns type identifier for this class.

## ACTION BEHAVIOR

**SoGLRenderAction**\
 Sets the color index for subsequent shapes rendered with **BASE\_COLOR** lighting.

## FILE FORMAT/DEFAULTS

```
ColorIndex {
index	1
}
```
