The earliest and most basic form of color theory is the color wheel created by Issac Newton. It is a wheel colors designed to help you in a way that any colors you pick go together. The most common color wheel is made up of twelve colors.
It begins with your three primary colors- red, yellow, and blue. Some say these three colors along with black and white are all you need for an entire palette.
Each primary has a warm shade and a cool shade. Warm colors represent things like fire. Cool colors represent things like water. How can you make a warm color like red, a cool color? It's not scientific but the coolor wheel is split into two sides, warm and cool, look to where it falls on the color wheel, is it leaning towards the cooler side or warmer side? A lot of it comes down to sight and perspective.
The only true way to tell if the color you are choosing is warm or cool is to play and test it for yourself.
By combining two of the primary colors you can create three secondary colors.
Red & blue = purple.
Red & yellow = orange.
Blue & yellow = green.
When you mix a primary color with its closest secondary color you will create tertiary colors. There are six tertiary colors in total,
Yellow & orange =yellow orange
Red & orange +red orange
Red & violet = red violet
Blue & violet = blue violet
Blue & green = blue green
Yellow & green= yellow green
These twelve colors are what makes up the color wheel. From here you can mix various color schemes we'll look at next week.
