"色" (pronounced "shiki" or "iro" in Japanese) means "color" in English. It refers to the visual perception of different wavelengths of light. Colors can be categorized into primary colors, such as red, blue, and yellow, and secondary colors, which are created by mixing primary colors. In various cultures, colors hold symbolic meanings. For example, in Chinese culture, red symbolizes good fortune and happiness, while in Western cultures, it can represent love or danger. Understanding "色" helps in art, design, and communication, as colors can evoke emotions and convey messages.
