To match grey in a visually appealing way, consider pairing it with complementary colors like black, white, or navy for a classic, sleek look. For a warmer, more inviting feel, combine grey with shades of red or orange. Alternatively, for a more muted and sophisticated style, grey can be paired with pastel colors or neutral tones. It's also important to consider the texture and pattern of the fabrics when mixing grey with other colors.
