PARAMETERS
       red, green, blue
	      Specify new red, green, and blue values for the current color.

       alpha  Specifies a new alpha value for the current color.  Included
	      only in the four-argument glColor4 commands.

       void glColor4uiv( const GLuint *v )
       void glColor4usv( const GLushort *v )

PARAMETERS
       v      Specifies a pointer to an array that contains red, green, blue,
	      and (sometimes) alpha values.

DESCRIPTION
       The GL stores both a current single-valued color index and a current
       four-valued RGBA color.	glColor sets a new four-valued RGBA color.
       glColor has two major variants: glColor3 and glColor4.  glColor3
       variants specify new red, green, and blue values explicitly and set the
       current alpha value to 1.0 (full intensity) implicitly.	glColor4
       variants specify all four color components explicitly.

       glColor3b, glColor4b, glColor3s, glColor4s, glColor3i, and glColor4i
       take three or four signed byte, short, or long integers as arguments.
       When v is appended to the name, the color commands can take a pointer
       to an array of such values.

       Current color values are stored in floating-point , with unspecified
       mantissa and exponent sizes.  Unsigned integer color components, when
       specified, are linearly mapped to floating-point values such that the
       largest representable value maps to 1.0 (full intensity), and 0 maps to
       0.0 (zero intensity).  Signed integer color components, when specified,
       are linearly mapped to floating-point values such that the most
       positive representable value maps to 1.0, and the most negative
       representable value maps to -1.0. (Note that this mapping does not
       convert 0 precisely to 0.0.)  Floating-point values are mapped
       directly.

       Neither floating-point nor signed integer values are clamped to the
       range [0,1] before the current color is updated.	 However, color
       components are clamped to this range before they are interpolated or
       written into a color buffer.

NOTES
       The initial value for the current color is (1, 1, 1, 1).

       The current color can be updated at any time.  In particular, glColor
       can be called between a call to glBegin and the corresponding call to
       glEnd.

ASSOCIATED GETS
       glGet with argument GL_CURRENT_COLOR
       glGet with argument GL_RGBA_MODE
