## Python Specification

``glutGetColor`` | `(` | ``cell`, `component`) → `None``

## Parameters

`cell`
  Color cell index (starting at zero).
`component`
  One of `GLUT_RED`, `GLUT_GREEN`, or `GLUT_BLUE`.

## Description

`glutGetColor` retrieves a red, green, or blue component for a given color index colormap entry for the current window's logical colormap. 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. For valid color indices, the value returned is a floating point value between 0.0 and 1.0 inclusive. `glutGetColor` will return -1.0 if the color index specified is an overlay's transparent index, less than zero, or greater or equal to the value returned by `glutGet(GLUT_WINDOW_COLORMAP_SIZE)`, that is if the color index is transparent or outside the valid range of color indices.
