Step-by-step explanation:
The term used for referring to each of the basic colors of the spectrum is hue. Hues appear on the visible spectrum as pure colors and can be divided into different categories, which are primary, secondary, and tertiary colors. For example, primary hues such as red, yellow, and blue can be mixed to produce secondary hues: orange (red and yellow), violet (blue and red), and green (blue and yellow). Tertiary hues are created by mixing a primary color with a secondary color, creating hues like yellow-green or blue-violet. Additionally, analogous colors are colors next to one another on the color wheel, which tend to blend together smoothly, while complementary colors are colors directly opposite each other on the color wheel and stand out boldly when placed together.
