, alpha
Specify new red, green, blue, and alpha values for the current color. The initial value is (1, 1, 1, 1).
The GL stores a current four-valued RGBA color. glColor
sets a new four-valued RGBA color.
Current color values are stored in fixed-point or floating-point. In case the values are stored in floating-point, the mantissa and exponent sizes are unspecified.
Neither fixed-point nor floating-point 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 the color buffer.
