The word “colour” (spelled “color” in American English) refers to the characteristic of visual perception that allows individuals to distinguish objects based on the light they reflect, emit, or transmit. This property is determined by the wavelength of light and is commonly categorized into various hues, such as red, blue, green, and yellow. Colour can also refer to the appearance or quality of something, often used in the context of art, design, and aesthetics. Additionally, “colour” can denote emotional or symbolic meanings, as in cultural associations or personal expressions. In a broader sense, it can describe diversity and variety in various contexts, such as in language, experience, or perspectives.
