Fundamental colors are primary hues that make up the basis of all other colors. Synonyms for this term include essential colors, basic colors, primary colors, foundational colors, core colors, and elemental colors. These colors consist of red, blue, and yellow and cannot be created by mixing any other colors. From these colors, secondary colors can be created by combining them in different ratios. To make green, blue is mixed with yellow. To make orange, red is combined with yellow. Finally, to make purple, blue is mixed with red. While there are many different shades of colors that can be created from the three fundamental colors, these basic colors provide the building blocks for all of them.
