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 vari-
ants specify new red, green, and blue values explicitly and set the
current alpha value to 1.0 (full intensity) implicitly. glColor4 vari-
ants 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 posi-
tive representable value maps to 1.0, and the most negative repre-
sentable value maps to -1.0. (Note that this mapping does not convert 0
