Too often we rely on color to add interest to a space. If our living room is too bland, what is the first thing we think to do? Paint! Or add bright accent pillows or curtains. Don't get me wrong, I love color, but i think neutrals are too overlooked sometimes. When I was starting my interior design career I worked for a designer named Betsy Brown. She was the one that opened my eyes to the elegance of neutrals.
When you decorate solely with neutrals, you will start to notice things that are often overlooked. Balance and pattern become main players in the design of your space. You will start to notice that there are countless different shades to use. Texture is a huge part of using neutrals too. When you eliminate color you will see the roughness of unfinished wood, in contrast with the softness of linen and the shiny-ness of a mirror or vase. It really is a brilliant and elegant way to design a space.
Of course you can always add pops of color if you want. I love this grey-blue.
Don't be afraid to go dark with it either. Charcoal and black are beautiful too.
Like I said, I am a big fan of color, but I just love how powerful neutrals can be on their own as well.
