GL contains subroutines designed to define the attributes for drawing primitives. These subroutines set the current color in either color map mode or RGB mode; the current linestyle, width, and color for line drawings; and the current fill pattern for solid objects. The shademodel subroutine sets the shading model for drawing shaded polygons.
You may want to read about the effects of certain attributes in "Creating Lighting Effects" and in "Working in Color Map and RGB Modes".
To read about the effects of certain attribute subroutines, see Creating Lighting Effects in GL and Working in Color Map and RGB Modes in GL.
