What Colors Does Yellow and Green Make?

Yellow and green are analogous colors because they reside close to each other on the color wheel, and in fact, they are only separated by one color; yellow-green.

Yellow-green is a tertiary color you will get when you mix yellow and green. This color can also be referred to as ‘chartreuse.’ 

Here we investigate the different shades you can get when you mix yellow and green and how this is influenced by color theory.

What do Yellow and Green Make?

When you mix yellow and green paint together, you will get a color called ‘chartreuse’ or ‘yellow-green’. This is a tertiary color because it is created by combining primary and secondary colors. In this example, yellow is the primary color, and green is the secondary color.

A primary color is defined as being the source of all other colors, which can only be made using pigment rather than mixing other colors together. A secondary color is a color that is made by mixing two primary colors together. Here, our secondary color, green, is made by mixing 50% blue with 50% yellow.

When you mix green and yellow together at a ratio of 50% green to 50% yellow, you are actually mixing 25% blue with 75% yellow since green is a mix of blue and yellow. When green and yellow are mixed in even amounts, the resulting color is yellow-green. This tertiary color is exactly halfway between yellow and green, so it sits sandwiched between these two colors on the color wheel.

The Meaning of Chartreuse

Chartreuse is a vivid yellow-green color, made from half yellow and half green. However, since green is made up of half yellow and half blue, we can see that in terms of primary colors, chartreuse comprises three-quarters yellow and one-quarter blue. This means that despite being made up of warm and cool temperature colors, the overwhelming feeling of chartreuse is warm because it is predominantly warm.

However, if you consider color temperature on a sliding scale, chartreuse could be considered a cool variety of yellow since it is much cooler than shades of yellow that contain a hint of orange or red, such as mustard. You could also consider chartreuse to be a warm shade of green since it is warmer than comparable cool greens such as mint or emerald.

Since chartreuse is made up of yellow and green, it can exude feelings and emotions associated with these colors. Like green, chartreuse feels fresh and lively, and it can create a sense of vitality and energy.

It is also linked to spring colors, which we associate with growth and new beginnings. Chartreuse also possesses some of the energy of yellow; for example, it feels sunny and positive and can evoke feelings of enthusiasm and youth.

What Colors Can You Make with Green and Yellow?

If you’re mixing green and yellow together, the resulting color is going to depend on what type of green and yellow you started with, and what proportion of the colors are going in the mix.

For example, if you mix 80% green with 20% yellow, then the color you get is going to be more green than it is yellow. In this case, you’ll get a yellow-tinged shade of green which looks something like dark lime green.
