Grey is a neutral color that combines well with practically any other color, very much the same as black. Color schemes with grey depend mostly on the shade of grey worn. Light grey shows contrast of brighter colors well, while darker grey combines better with lighter colors.
Light grey displays purples, yellows, blues, and reds well, while dark grey is a good base for silvers, whites, blacks and pastel colors. Both light and dark grey enhance patterned and textured garments in contrast. Men's suits in grey are a good "canvas" to present blue, white, pink or yellow shirts combined with plain, patterned or colorful contrasting ties.
