The vividness, brightness or saturation of a color is referred to as:

• A. Level
• B. Texture
• C. Intensity
• D. Porosity

Answer: (C)

Intensity describes the vividness, brightness, or saturation of a color. It’s about how pure or concentrated the hue appears. When intensity is high, the color looks bold and vivid; when it’s low, the color seems muted or dull because some gray or dilution has reduced the color’s saturation. In hair coloring, you’ll notice this as pure, vibrant shades versus softer, washed-out tones after dilution or when a color is toned down. By comparison, Level is about how light or dark the shade is, Texture is the feel or surface quality, and Porosity is about how much moisture or pigment the hair can absorb—factors that influence application and longevity but not the color’s vividness itself.
