How to get the colour turquoise

Updated April 17, 2017

Whether you are using acrylic paint for a craft project with your children, house paint for a wall in your home or oil paint for a clean canvas, making the colour turquoise is fairly easy and extremely rewarding. Using a colour-mix ratio of blue and green, you can achieve the shade of the sea, one of the most captivating colours of all time.

Determine how much paint you are going to need for the project. If you are painting an accent wall, you might want to mix a gallon of house paint. If you are painting a beach scene on a 30 by 25 cm (12 by 10 inch) canvas, you may only need 118 ml (1/2 cup) of acrylic paint.

Use a 2-to-1 ratio of blue and green -- 2 parts blue and 1 part green. For example, if you need a gallon of turquoise paint, mix 3 litres (2/3 gallon) of blue paint and 1.5 litres (1/3 gallon) of green paint. If you're painting the water on a beached-themed canvas, mix 79 ml (1/3 cup) of blue paint and 39.5 ml (1/6 cup) of green paint. Mix your paint in a sturdy container with a lid, and make sure the colour is consistent throughout.

Apply some paint to a wall, piece of paper or canvas. Allow it to dry, and decide if the shade is to your liking. If you want to make a slight variation, mix in more blue or more green. You could also add some white for a softer tone. Keep track of the proportions so that you can mix more if needed.

Paint your project. Be sure to cover the container when you are not using the paint to prevent it from drying out too quickly. Store the paint in a cool, dry place.


Don't be afraid to experiment with all the variations of turquoise. There are many shades that fall within the turquoise range, such as ultramarine, phthalo blue, cyan and viridian green. For more advanced colour mixing, try blending variations of these shades of paint, which can be found at your local arts and crafts store.


If you choose to branch out and create a darker, stormier shade of turquoise, you can add a tiny bit of black. Only use a small portion at a time as it can dramatically alter the colour.
