Intensity--also referred to as chroma or saturation--is the degree of purity of a hue or the brightness or dullness of a color. In a high-intensity color scheme, all or almost all of the colors are used at a high level and are extremely bright and concentrated with no addition of other colors.
Implications
Most colors are said to carry physiological, cultural, personal, emotional and expressive implications. Children generally prefer brighter, bolder, happier palettes. Men in most cultures seem to prefer cooler colors, whereas women prefer warmer colors overall. A room’s decor makes a statement about its owners.
Balance and Proportion
Lovers of drama who want to use strong colors should pair them up with strong partners. Maintain the balance of the room’s decor by keeping the intensities of color equal or nearly equal in other components. For example, if you paint your walls in a pure, bright turquoise, the upholstery or other major elements in the room would need to be equally strong in order to be balanced. Pairing colors of different intensities often creates a feeling of being out of balance. Alternatively, your sofa can be white, but if you paint the walls a deep color, find balance through an area rug, chair or jewel tone throw pillows.
Primary Colors
Primary colors (red, blue and yellow) are considered to be the most intense of all the hues. In graphic arts, high-intensity primary colors are often intentionally used to increase the impact of a design. Many parents decorate baby, toddler or children’s rooms in bold, primary colors, sometimes accented by black and white.
Uses
When decorating, use high-intensity colors to draw attention. These colors give the appearance of carrying more weight than less saturated, low-intensity or visually simpler areas. Very bright or saturated colors generate more energy and tend to be more dynamic and richly elegant. With dark wood furnishings, the choice of a bright wall color raises its level of richness for an effective complement. Make a large room seem cozier and more intimate by using low-value, high-intensity, warm colors.
