Black, White, Grey, Black, White, Grey, blahhh

I can't help, and I can't stop myself, I wear/buy black, white, grey pretty much exclusively in the winter. It bugs even me, that's how extreme it is. I remember being 19 and coming home from a shopping excursion to have my mom say, you bought ANOTHER white shirt...how is this different from the other 20 in your closet. And she was right. I love color. I don't know why I am so drawn to black, white, grey. Yes they are staples, neutrals, etc, etc. But its not like a green sweater would look weird with black, white, or grey pants?
