Which statement best describes the effect of dark cool colors?

Dark cool colors, such as deep blues, greens, and purples, are often associated with tranquility and calmness. These colors can evoke a sense of restfulness and relaxation, making them ideal for spaces meant for unwinding, such as bedrooms or meditation areas. The psychological impact of these hues contributes to a soothing environment, which can help to alleviate stress and promote a sense of peace.

In contrast, other color effects, such as making a figure look larger or creating a sense of activity, pertain more to warm or bright colors, which energize and draw attention. Distracting from the main focus of a room relates to how colors interact with spatial perception and emphasis, which is less connected to the restful nature of dark cool colors.
