Yes, gray can have blue in it.
Gray is a neutral color, and like other neutrals, it often has undertones. These undertones influence the overall appearance of the gray. Blue is one of the common undertones found in gray paint colors. Other undertones can include green, violet, and taupe. Recognizing these undertones is essential when choosing a gray for a specific purpose, such as painting a room, to ensure it complements the existing colors and lighting. A gray with a blue undertone will appear cooler compared to a gray with a warmer undertone like taupe.
