Despite the matching shirt and necktie combinations that were popular for a while, a well-dressed man avoids monochromatic looks. Any composition that's too similar in color cannot accomplish what should be the objective of all dressing, which is to lead the observer's eye to the face.
The best looks vary the tones of jacket, shirt and necktie, with the dress shirt normally providing the lightest tones. One classic combination is a dark jacket, light shirt and intermediate toned necktie like the ensemble in the photo from cloth merchant Holland & Sherry. Another is the dark necktie, light shirt and intermediate toned jacket.
Flatter yourself by mixing dark and light.
