## 8.1 glutSetColor

`glutSetColor` sets the color of a colormap entry in the layer of use for the current window.

Usage

    void glutSetColor(int cell,
                      GLfloat red, GLfloat green, GLfloat blue);

`cell`
  Color cell index (starting at zero).
`red`
  Red intensity (clamped between 0.0 and 1.0 inclusive).
`green`
  Green intensity (clamped between 0.0 and 1.0 inclusive).
`blue`
  Blue intensity (clamped between 0.0 and 1.0 inclusive).

Description

Sets the `cell` color index colormap entry of the current window's logical colormap for the layer in use with the color specified by `red`, `green`, and `blue`. The layer in use of the current window should be a color index window. `cell` should be zero or greater and less than the total number of colormap entries for the window. If the layer in use's colormap was copied by reference, a `glutSetColor` call will force the duplication of the colormap. Do not attempt to set the color of an overlay's transparent index.
