Seems like a no-brainer, doesn’t it? How could you go wrong with simple, classic white?
Before you go and paint your house entirely white (“it’s modern!”), read this post. Yes, white can be serene, beautiful, and (of course) modern, but there’s a fine line between “fresh and clean” and “hospital antiseptic.”
White is the ultimate neutral. It matches everything. But many consider it a “non-color” due to its inherent blandness. The great thing about white is that it serves as a perfect backdrop to any other color that you want to use, and it can also be used on its own (with an abundance of caution).
The most classic combination: black and white.
