Colors that match mauve include other shades of purple, shades of green, gray and blue. Green is mauve's complementary color, while purple variations match because of similar color elements.
Mauve is a pale purple color that comes in various shades. It features tones of gray and blue, so gray is a good neutral color to pair with mauve. Blue can be used to accent mauve; however, purple's complementary color, green, breaks up color monotony and brings interest to paintings or documents, such as slide show presentations.
Adding white, gray, or black to a mauve base can provide different shades of purple that also match mauve.
