Those are some lovely grey pieces. I tend to think that maybe grey is your white! And a very sophisticated look it can give.
I really like grey but have to be careful with it. I actually think charcoal is one of my very best colours/ neutrals -- it's instantly flattering to me, at least in the correct tone.
So, I tend to purchase and wear quite a lot of grey when it is available in winter. (Grey is a bit like brown in terms of availability here. Some years you can't go anywhere without running into it..and other years, it is impossible to find.)
But...like black...worn in large doses too consistently, grey can make me feel sad and depressed...especially on our grey days. (It does not make me feel this way on sunny summer days, especially in these lovely soft lighter shades that you picture, worn in combination with whites and silver; it is only in winter that it causes me to feel this way.)
My wardrobe is hugely weighted to blues, in different shades/ tones/ intensities, it is true, but for me, blue is like black is to you -- I really couldn't get dressed without it. Even my greys are mostly on the blue side. I do have other colours, but they are all accents to the main event.
