Because primary pretty much means main. And the primary colors are main because they make the other colors. Go figure:
Blue + Yellow = Green
Red + Blue = Purple
Yellow + Red = Orange
Definition? O.K.
List of primaries? Wrong.
Printing: yellow, cyan, magenta, plus black to make solid blacks.
Televison: red, green blue.
All wrong :)
There really is no such thing as "primary" colors. All colors have a warm and cold value which cannot be mixed. If you mix blue + yellow and they are not of the same value, you get brown. If you mix a warm blue with a warm yellow you will get a warm green. Cold red + cold yellow = cold orange. If you don't understand this, I highly recommend the book "Blue and Yellow Don't Make Green" by Michael Wilcox.
Colors that aren't primary colors are called secondary colors, intermediate colors, or tertiary colors, depending on how they are created.
Primary colors are called "primary" because they are fundamental colors that cannot be created by mixing other colors. They are considered the building blocks for all other colors in the color wheel. Mixing primary colors together can create a wide range of secondary and tertiary colors.
Primary colors are called primary because they are the base colors that can be used to mix and create all other colors. In the additive color system, the primary colors are red, green, and blue, while in the subtractive color system, the primary colors are cyan, yellow, and magenta. Mixing these primary colors in different combinations can produce a wide range of other colors.
When two primary colors are mixed together, the resulting color is called a secondary color.
The colors in between primary and secondary colors on the color wheel are called tertiary colors. These colors are created by mixing a primary color with a neighboring secondary color. For example, mixing red (primary) with orange (secondary) creates a tertiary color known as red-orange.

Primary Colors.
The colors in between primary and secondary colors on the color wheel are called tertiary colors. These colors are created by mixing a primary color with a neighboring secondary color. For example, mixing red (primary) with orange (secondary) creates a tertiary color known as red-orange.
Because you can create all the other colours using different combinations of the primary
Primary light colors combined to produce white light are called additive colors. The primary additive colors are red, green, and blue (RGB). When these colors are mixed together at full intensity, they create white light.
Secondary colors are called so because they are created by mixing together two primary colors. These colors are green, orange, and purple, which are produced by combining specific pairs of primary colors (red, blue, and yellow). Their name reflects the fact that they are derived from primary colors.
When primary colors of paint (red, blue, yellow) are mixed together, they produce secondary colors (orange, green, purple).
A mixture of the primary colors of pigments, which are red, blue, and yellow, is called a tertiary color. Mixing these primary colors together in various combinations can create a wide range of secondary and tertiary colors.
When combined in equal amounts, the three primary colors of light produce white light.
