Neckties can add polish and a pop of color to any men's dress shirt. Choosing the right necktie requires an understanding about color harmony. When matching a necktie to a gray long-sleeved shirt, the neutral tone of gray allows for many necktie color options.
Neutral color schemes are essential for any wardrobe, as they can be matched with virtually any color. According to Colormatters.com, basic color theory deems neutrals as navy blue, black, gray and brown. Various shades of neutrals can be matched with any color hue on the color wheel.
Create a bolder look by pairing a gray long-sleeved shirt with a vibrantly hued necktie. According to Tara Wickwire of Gap, bold colors are defined as the shades of any color that are bright and commanding. Examples of bold colors include royal blue, kelly green, fire engine red, magenta and royal purple. These colors can be paired with a long-sleeved gray shirt to give an outfit a bright, bold look.
For a softer, more gentle look to an outfit, match a gray long-sleeve shirt with cooler-toned neckties. Examples of cool-toned colors include pastel hues such as pale pink, violet, peach and light green. When pairing a gray long-sleeved shirt with a cool-toned necktie, the overall look will be soft and a good blend.
Keep a neutral color scheme going by pairing a gray long-sleeved shirt with a neutral-colored necktie. For example, wear black pants with the gray long-sleeved shirt and a dark gray, charcoal or silver tie. This look is a sleek and professional option for an outfit.
