102 v Specifies a pointer to an array that contains red, green, blue,
103 and (sometimes) alpha values.
104
106 The GL stores both a current single-valued color index and a current
107 four-valued RGBA color. glColor sets a new four-valued RGBA color.
108 glColor has two major variants: glColor3 and glColor4. glColor3 vari‐
109 ants specify new red, green, and blue values explicitly and set the
110 current alpha value to 1.0 (full intensity) implicitly. glColor4 vari‐
111 ants specify all four color components explicitly.
112 glColor3b, glColor4b, glColor3s, glColor4s, glColor3i, and glColor4i
114 take three or four signed byte, short, or long integers as arguments.
115 When v is appended to the name, the color commands can take a pointer
116 to an array of such values.
117 Current color values are stored in floating-point , with unspecified
119 mantissa and exponent sizes. Unsigned integer color components, when
120 specified, are linearly mapped to floating-point values such that the
121 largest representable value maps to 1.0 (full intensity), and 0 maps to
122 0.0 (zero intensity). Signed integer color components, when specified,
123 are linearly mapped to floating-point values such that the most posi‐
124 tive representable value maps to 1.0, and the most negative repre‐
125 sentable value maps to -1.0. (Note that this mapping does not convert 0
126 precisely to 0.0.) Floating-point values are mapped directly.
127 Neither floating-point nor signed integer values are clamped to the
129 range [0,1] before the current color is updated. However, color compo‐
130 nents are clamped to this range before they are interpolated or written
131 into a color buffer.
132
134 The initial value for the current color is (1, 1, 1, 1).
135 The current color can be updated at any time. In particular, glColor
137 can be called between a call to glBegin and the corresponding call to
138 glEnd.
