I am wearing a pair of black work out pants (thin cotton, tie waist) and a light blue t-shirt.

Is that symbolic of balance between good health and bad health? LOL, I dunno, but it is comfortable.
I have no problem wearing black, the same as I have no problem wearing lighter colors (with the exception that reds & yellows make my skin look sickly unless I am tanned

).
There is a "Rainbow Coalition" that uses colors through visualization to create inner balance, among other things...then there are others who see black as a definitive projection of evil, the same as they see white as a definitive projection of good...to me there are certain associations that I will not deny colors and their effects on our moods but I won't allow them to rule what I wear or the color of my furnishings...if I like it and it looks good with everything else, I'll let it stay around.
