Well, there are actually 3 types of colours:
Primary: Main Colours (Red, blue and yellow)
Secondary: Colours made from combining 2 Primary colours (Purple, orange and green)
Tertiary: Colours made by mixing Primary and secondary colour (Yellow-orange, teal, yellow-green)
Hope this is what you were looking for.
When two colors are next to each other on the color wheel, they are called analogous colors. These colors are closely related and typically work well together because they share similar undertones.
analogous
The three colors that are next to each other on a 12 part color wheel are called analogous colors. Often times, 1 of the 3 colors dominates over the other two, such as a combination cluster like yellow-green, yellow, and yellow-orange. Analogous colors, along with complementary and primary colors, are a very important basic element of color theory.
The secondary colors on the color wheel are orange, green, and violet. These colors are created by mixing two primary colors together.
When you mix two colors together, you create a new color through a process called color mixing. The resulting color will depend on the primary colors you are mixing. Mixing colors from opposite ends of the color wheel can create secondary colors, while mixing colors closer together can create variations or tones of those colors.
When you mix a primary color and a secondary color together, it is called a tertiary color. This occurs by blending two adjacent colors on the color wheel.
On the color wheel green is a secondary color. It is a mixture of two primary colors, yellow and blue.
A secondary colour is two primary colours mixed together on the colour wheel.
The different kinds of color harmonies include analogous colors (colors that are next to each other on the color wheel), complementary colors (colors that are directly across from each other on the color wheel), triadic colors (colors that are evenly spaced around the color wheel), and split-complementary colors (one base color paired with two colors adjacent to its complement).
The opposite of red on the color wheel is green. These two colors are complementary, meaning they are positioned directly across from each other on the color wheel and create a high contrast when used together.
yellow-orange, because you always say the primary color first when mixing them with secondary colors.
When two primary colors are mixed together, the resulting color is called a secondary color.
