Color Matters says that when green and yellow are mixed together, they make a colour called “yellow-green.” You can also change the colour by adding different amounts of the two colours. For example, if more green is used, the colour will be more green-yellow than yellow-green.
Color Matters says that the colour yellow-green is a tertiary colour. When you mix a primary colour with a secondary colour, you get a tertiary colour. In this case, the main colour is yellow, and the secondary colour is green, which is made by mixing blue and yellow. Other tertiary colours are red-orange, red-purple, and blue-purple, which is also called blue-violet.
