Tertiary colors are created by mixing a primary color with a secondary color in equal amounts. There are three tertiary colors, and they include yellow-green, blue-green, and blue-purple.
In art and design, tertiary colors are often used to create a range of different hues and shades by mixing them together in different proportions. They can also be used to create analogous colors, which are a group of colors that are next to each other on the color wheel.
In graphic design and printing, tertiary colors are used to create images and designs using a process called CMYK (cyan, magenta, yellow, and black). These colors are used in combination with black to create a wide range of different shades and tones.
Overall, tertiary colors are created by mixing a primary color with a secondary color in equal amounts, and are used in art, design, and printing to create a range of different colors and shades.
