The Science Behind What Two Colors Make Blue
## Introduction
The primary colors – red, yellow, and blue – form the foundation for all of the other colors in our visible spectrum. This means that understanding the science of what two colors combine to make blue is an important part of understanding the basics of color creation. In this blog, we will explore the scientific principles behind what two colors make blue, and how you can use the information to mix other colors in your artwork.

## The Making of Blue
Blue is a primary color, meaning it cannot be created by mixing any other colors together. While this may seem confusing, it’s actually because blue is the only primary color that contains no red or yellow. Every other color, including green and purple, is created by mixing two primary colors together.

So what two colors make blue? In short, none. But that doesn’t mean you can’t create blue from other colors. To understand how this works, we need to take a closer look at the color wheel.

## Color Wheel Theory
The color wheel is a tool used by artists and designers to understand the relationship between different colors, and how they can be mixed to create entirely new colors. The basics of the color wheel are simple: all of the primary colors are located at equal distances from each other, forming a circular pattern.

When two primary colors are mixed together, they form a secondary color. For example, when red and yellow are mixed together, they create the secondary color of orange. But when two secondary colors are mixed together, they create tertiary colors. This is where things get a bit more complicated.

When two tertiary colors are mixed together, they form what is known as a quaternary color. And this is the key to understanding what two colors make blue. Because blue is a primary color, any combination of two tertiary colors that involve blue will form a quaternary color that includes blue.

For example, when blue-green and blue-violet are mixed together, they form a quaternary color that contains both shades of blue. This is also true for any other combination of tertiary colors that involve blue, including yellow-green and violet-red.

## Conclusion
As you can see, the science of what two colors make blue is complicated but fascinating. The science of color mixing is an important part of any artist’s education, and understanding how to mix other colors to create blue can help you take your art to the next level. With a little bit of practice and patience, you can learn to mix a full range of colors and create beautiful, vibrant pieces of art.
