Top designers often prefer colors that are considered timeless and versatile, such as navy blue, black, white, and gray. These colors are not only visually appealing but also allow for a wide range of design applications. Designers also tend to favor colors that evoke a sense of luxury or sophistication, such as deep reds, greens, and purples. The choice of color often reflects the designer's personal style and the intended message or aesthetic of the design project.
