How to Create Gray Paint

Quck answer

To make gray paint, you can mix black and white paint together in varying proportions. Start with a small amount of black paint and gradually add white paint until you achieve the desired shade of gray. Remember to mix the paints thoroughly to ensure an even color. You can also experiment with adding other colors, such as blue or brown, to create different shades of gray. Keep in mind that the amount of black and white paint you use will determine the intensity of the gray color. Practice and experimentation will help you find the perfect gray shade for your painting projects.


If you believe that gray is simply a combination of black and white, you will not be able to fully appreciate the nuances of this complex decorating color. Gray is classified as a neutral color, similar to brown. It is essentially the result of blending primary colors together; when this is done to an extreme extent, black is produced. While gray is neutral, it typically has a noticeable hue that is created by the colors used to mix it.

Warm vs. Cool Grays

Prior to mixing gray for your walls or trim, take into consideration the surrounding color scheme. If the predominant colors in the decor are red, yellow, orange, or brown, the scheme is considered warm. On the other hand, if the majority of colors are blue, green, or violet, it is considered a cool color scheme. You can mix your own gray in either a warm or cool tone, depending on the colors you use. However, it is best to combine warm gray with warm colors and cool gray with cool colors. Also, consider the desired level of lightness for the gray, as this will help determine the colors to use for mixing, as well as the best type of base to utilize.

Mixing Black and White for Neutral Gray

By adding black pigment to white paint, you can create a neutral gray that is neither warm nor cool, allowing you to use it anywhere. Here is the process for mixing black and white to create a neutral gray:

  1. Add black pigment or paint to white paint, and have a color reference on hand to determine when you have achieved the proper mixture.
  2. If you desire an off-white shade, add the black in small increments, a few drops at a time. For a deep gray, add the black in larger increments.
  3. Thoroughly stir the mixture before comparing the color to your reference, and add more black as needed until you achieve the final shade.

Creating Gray With Primary Colors

When the primary colors – yellow, red, and blue – are mixed together, they produce gray or brown. If you mix them to create gray, the predominant colors will determine the tint of the final mixture and whether it is a cool or warm color. It is helpful to make a test batch in a small container, measuring the proportions of pigments used. Once you have achieved the proper mixture, you can use the same proportions to mix an entire can of paint.

Follow these guidelines to create gray paint:

  1. Begin by mixing blue and red pigments in approximately equal proportions to produce purple. Use more blue for a cooler mixture, and more red for a warmer color.
  2. Add yellow pigment to adjust the tone of the gray as desired. The more yellow you add, the lighter the mixture will become.
  3. Keep a color chip nearby to compare and match your color blend.
  4. If the gray is too dark, add white; if it is too light, use black pigment to create a darker shade.

Tip

If you want to create a deep gray, such as slate, mix the pigments in a clear paint base. Alternatively, use a white base to produce lighter, pastel grays.
