If u want to access the color from the fixed function pipeline in a fragment shader theres already a buildin read-only varying in GLSL:
varying vec4 gl_Color;
varying vec4 gl_SecondaryColor;
For a full list of buildin variables at ur disposal for free take a look
here
Take a look at
these fragment shaders and the
corresponding JOGL2 code where I use the fixed function material properties to set GL_FRONT later on used in the fragment shader ... hope that helps

Other than that u can ofcourse set a color uniform explicitly from ur code. Take a look
here where I set a lightcolor array to individual colors for later shader use.
