HansO,
That comment bears a re-run of the famous ditty -
Sung to the tune of "Red & Black", from Les Miserables -
Red - for show to be in the groove!
Black - the dark of Rockets right!
Red - like blood is slow to move!
Black - allows the speed of light!
Red - I feel my soul is sick!
Black - the one that red can't bend!
Red - the color of the dog dick!
Black - the color remaining at the end!
