The word "red" describes the hue of a color. When referring to colors, hue is the attribute that distinguishes them from each other, such as blue, green, yellow, and red. The perception of color is affected by the wavelength of light that is reflected or absorbed by an object. Objects that appear red are reflecting or emitting light in the longer wavelength range of the visible spectrum. Understanding the terminology and characteristics of color can help in describing and identifying different shades and variations.
