Since starting my window streatments business almost three years ago I can count on one hand the times I have paired Yellow with something other than Gray.
Gray seems to be both the obvious and most popular color to pair with yellow.
But there are many other options to consider.
Yellow and Black
Yellow and Red
Yellow and Blue
Yellow and Brown
Yellow and Hot Pink
Yellow and Purple
Yellow and Green
Have a little fun with it! Explore the possibilities!
