This is tough, Michelle. I'm thinking about my own closet. I wish I could share the pics with you. I have:
1) A knit burgundy cowl neck - which I never pair with black. I love it with cream, tan/khaki and with brown. It is too dark to go with black and looks "off" that way.
2) A silk burgundy blouse - which has black rosette detailing at the neckline. I routinely pair this with black. Yes, it is dark. A string of pearls offsets this. (I also, just yesterday, discovered I could pair this with gray pants and a burgundy tweed jacket that is a direct match).
3) Burgundy leather boots - which I do pair with black skirts and dresses. I think this works because of the contrast of textures.
4) Cranberry tops of various materials - don't own anything in this color at the moment, because I overdosed on it awhile back. I would absolutely pair this with black. Cranberry, like burgundy, is a blue-red, but the intensity is different. Cranberry is brighter and not as muted.
5) True red - which is even brighter than cranberry. This is in the category of the color of the lipstick you wear, which I love on you so much. True red can be an orange-red (tomato - Angie wears this color a lot) or more of a blue-red (the color of a crayon that is labeled red, or a stopsign ;-). It is BOLD. I would and do wear this color with black.
