Black, white and red, is one of my "go to" color combinations.
Black and white makes for easy pattern mixing, for those of us who are not pros at it!
A more subtle pattern mix, and a darker shade of red
Also black and white, and in this case grey, are an easy choice for adding a pop of color with accessories
Whenever I am at a loss, or rushed, I'll probably turn up in some combination of black and white and red!
