Yellow is probably the only paint color that is naturally light, even in its most saturated form. Yellow is the color of the sun, heat and energy. People associate yellow with movement, bright dispositions, sunny afternoons and warm temperatures. Yellow paint, when not mixed with white or brown, is sometimes too intense for wall paint. Often yellow is dulled down when used in interior design. When used in paintings, yellow often signifies a positive outlook.
When lightened, blue is a delicate color that people associate with powder, babies, fresh air and the sky. Blue is the color of peace and calm. When paired with colors like gray, light blue is a gentle color with a Zen-like quality, that both soothes and reassures. Light blue is a receding color, and when painted on a wall can open up the room to make it seem larger.
Most of the so-called "neutral" colors are light colors. In color theory, neutrals include black, white and gray, and are not colors at all. However, for most people the term "neutral" denotes a category of colors that can easily be matched to any other color. For example, neutrals may include gray, cream, khaki, tan and beige -- all of which are easily matched to a wide variety of non-neutral colors. Neutrals are often light, in order to be less imposing and more flexible. Neutrals are often used in interior design because they are safe and conservative.
This frosty gray-green color is pleasing to the eye and associated with the fresh outdoors, so this is a color commonly used as the basis of sophisticated color schemes in interior design. When used in the context of a painting, sage most often represents plant life. However, light greens, especially when mixed with yellow, can also signify sickness or sickliness.
