Question

Discuss the three dimensions of colour?​

Answer 1

Answer:

The perception of color is often described by referring to three dimensions of the color experiences: hue, saturation, and brightness. Hue refers to the color quality of the light and corresponds to the color names that we use, such as orange, purple, green, indigo, yellow, cyan, aquamarine, etc. In fact, hue is the quality of color. A quality is a value that changes, but it does not make the value larger or smaller. When hue or color changes, it does not make sense to say that red has more or less hue than green. This is because color is a quality, not an amount.

Saturation refers to the purity of the light. The more saturated the stimulus, the stronger the color experience, and the less saturated, the more it appears white or gray or black—that is, achromatic. The classic example of saturation differences concerns the continuum from red to pink. Pink is a combination of red light and white light. The more white light is added, the less “red” the pink is. Eventually, the red may be so overwhelmed by the white that we barely notice the pink at all.

Hue and saturation can be represented as a color circle (see below). Along the perimeter of the circle, we find the monochromatic hues—red, orange, yellow, green, blue, indigo, and violet. As we head toward the center of the circle, we get less and less saturated colors. Thus, a deep red and a deep blue exist on the perimeter, but pink and baby blue exist toward the center.

Brightness refers to the amount of light present. The more bright an object is, the easier it is to see and to notice the colors. Brightness is the dimension that now goes vertically through the color circle. Brightness does have a relation to color—it is easier to see color at higher brightness values.

Use this activity to expolore how the dimensions of color relate to the color you experience.

Answer 2

Answer:

Explanation:

• Hue: It describes the color quality of light and corresponds to color names like orange, purple, green, indigo, yellow, cyan, aquamarine, and so on.

Hue is, in reality, the quality of color. Quality is a value that shifts, but not in a positive or negative way. It makes no sense to state that red has more or less hue than green when the hue or color changes. This is due to the fact that color is a quality, not a quantity.

• Saturation: The purity of light is referred to as saturation. The stronger the color experience, the more saturated the stimulus is, and the less saturated it is, the more it appears white, grey, or black—that is, achromatic.
• Brightness: The amount of light present is referred to as brightness. The easier it is to perceive and recognize the colors, the brighter the thing is. The dimension of brightness now runs vertically through the color circle. Color and brightness do have a relationship; color is easier to see at higher brightness levels.
