Cool colors generally include which of the following?

Cool colors are primarily associated with hues that evoke a sense of calm and tranquility, often resembling nature elements like water and sky. Blues, as a cool color, reflect these qualities and can help create a soothing environment. This category also includes greens and purples, which share similar calming attributes.

In contrast, the other colors listed, such as reds, yellows, and oranges, are typically classified as warm colors. These colors tend to generate feelings of warmth, excitement, and energy, which sets them apart from the tranquil effects associated with blues and other cool colors. Thus, blues stand out as the quintessential representative of cool colors in design and hairstyling.
