How to Mix Sky Blue Oil Paint

Mixing sky blue oil paint is a great way to add color variation to your painting. This blog post will teach you how to mix sky blue oil paint that can be applied through the entire spectrum of light and dark tones. 

How to Mix Sky Blue Oil Paint

Paint colors are made by mixing pigments, so choosing the correct pigment combinations is essential when you want to create a new hue. This bright hue can be used to create uplifting and cheerful paintings. Ultramarine blue and titanium white are two of the most common pigments used to make sky blue.

What Is Sky Blue Oil Paint?

The sky blue oil paint is a mixture of ultramarine and white flake paints. Ultramarine is very vibrant, so only small amounts are needed to create deep colors. Flake white paint is the brightest of all the whites and was popular in 16th-century Flemish paintings.

The process for mixing sky blue oil paint is simple and involves only two ingredients: ultramarine and flake white. Mix medium can thin the mixture if needed to flow from your brush onto the canvas surface more quickly.  A fair value requires mostly flake white, while a high value requires ultramarine.

What Is the Proper Mix?

The sky blue oil paint mix is a relative spectrum, and it will not match the color of any manufacturers’ sky blue. However, you can achieve a relatively close match if you remember that most artists began with yellow and red in their palette when mixing skylights for their paintings.

This means that they would add more flake white than ultramarine to achieve lighter values, such as in this example: To Mix Sky Blue Oil Paint 2 parts Ultramarine Light, 1 part Flake White.  A high-value mixture may be created by adding more ultramarine until the desired color is achieved: To Mix Sky Blue Oil Paint 2 parts Ultramarine Deep, 1 part Flake White.

A Step by Step Guide on How to Mix Sky Blue Oil Paint

Step 1: Determine How Much Paint to Use

The first step in creating your masterpiece is to determine how much paint you need. To mix a perfect sky blue, you’ll need X amount of sky blue oil paint and X amount of white oil paint. The easiest way to achieve this is by using the “rule of thumb.”

This rule basically states that for every ounce of color, you should have one ounce of the medium. In this case, let’s say we want 1/2 cup of sky blue oil paint. We can divide 1/2 by two and learn that we will need 1/4 cup of each color (sky blue + white). We may also want to prepare more paint than we think because sometimes you will have a different medium.

Step 2: Mix Your Sky Blue Oil Paint

Once you have determined how much oil paint you need, take a clean mixing surface and place your white oil paint in the center. Next, add your sky blue oil paint to the white oil paint and mix together until you have a pastel blue color. If the color is too light, add a small amount of sky blue oil paint to the mixture and if it is too dark, add a small amount of white oil paint.

Step 3: Mix Your White Oil Paint

Mix Your White Oil Paint

Once you have mixed your sky blue oil paint, the last step is to take a clean mixing surface and place your white oil paint in the center. Next, add your sky blue-white oil paint mixture to the white oil paint and mix together until you have a bright white color. If it still looks gray, try adding a touch more of the pastel blue-white oil paint; if it’s too blue, add more white.

Step 4: Add Yellow Ochre for Warmth

To give your sky blue oil paint a warmer tone, add yellow ochre to the mixture. Start by adding 1/4 teaspoon of yellow ochre and mixing it into the sky blue oil paint. Continue adding yellow ochre until you get the desired warmth and color for your sky blue oil paint.

The sky is a mixture of all colors in the spectrum, which means we should end up with a blue-green color when we mix all these pigments to create sky blue oil paint. This will help us achieve the desired color when mixing sky blue oil paint.

Step 5: Add Black Oil Paint to Create Indigo

The last step is to add black oil paint (or ultramarine blue) until you reach your desired darkness. How much black oil paint you will need depends on how dark you want your final result, so start by adding small amounts, mixing thoroughly after each addition until you find the perfect shade for your painting or project!

Step 6: Finishing Touch

To make your paint mixture the perfect consistency, add a small amount of oil. The amount of oil you’ll need depends on how thick or thin you want your paint to be. If it’s too thick, add a tiny amount of linseed oil and continue mixing until you get the perfect consistency for your project.

  • To make the paint matte, add a small amount of turpentine or linseed oil to it. For a glossy finish, add the varnish.


  • Be sure to mix oil paint in a well-ventilated area.
  • Make sure the paint is out of reach of children or pets. The chemicals in oil paints are hazardous if ingested or inhaled.

What Are the Advantages of Using a Mixed Batch for Sky Blue Oil Paint Instead of Single Colors?

When it comes to painting, there are a lot of decisions to be made. For example, what color should you use for the sky? How can you make sure that the colors you choose will work well together?

Second, mixing your paint allows you to use high-quality pigments. Single colors may not have all the properties you need for your painting. By combining different colors, you can create paint with precisely the characteristics you need.

Finally, mixing your paint can be more economical. You can purchase pigments and other ingredients in bulk, which can save you money in the long run.
