What is the term for a particular color?

The term that specifically refers to a particular color is "hue." In color theory, hue defines the aspect of color that allows us to classify it, for example, red, blue, green, and so on. It denotes the basic color identity and is an essential part of the color wheel used in design and artistry.

While other terms such as tint, shade, and chroma relate to color, they do not describe the color itself. A tint refers to a color mixed with white, lightening it, whereas a shade refers to a color mixed with black, darkening it. Chroma relates to the purity or intensity of a color but does not specify the color itself. Therefore, "hue" is the correct term that encompasses the concept of a specific color.
