How to Mix Paint to Make Grey?

Published in Painting Techniques 3 mins read

To make grey paint, you typically combine black and white paint, adjusting the proportions for your desired shade. However, you can also achieve grey by mixing complementary colors or primary colors.

Methods for Creating Grey Paint:

Here are a few methods to create grey paint, each offering a slightly different result:

1. Mixing Black and White Paint

  • Neutral Grey: The simplest method is to combine black and white paint. Start with white paint and gradually add small amounts of black paint until you achieve the desired shade of grey. Adding too much black initially can quickly darken the mixture beyond your intended color.

  • Light Grey: Use a much larger quantity of white paint compared to black.

  • Dark Grey: Use a larger quantity of black paint compared to white.

2. Mixing Complementary Colors

  • Flat Grey: Mixing complementary colors (colors opposite each other on the color wheel) can create a more complex, "flatter" grey. Examples include:

    • Red and Green
    • Blue and Orange
    • Yellow and Purple

    Start with equal parts of each color and adjust the ratio until you achieve your desired grey. The resulting grey will often have subtle undertones of the component colors.

3. Mixing Primary Colors

  • Primary Grey: Combining all three primary colors (red, blue, and yellow) can also produce a grey. This method is more complex and requires careful adjustment of the ratios to avoid ending up with a muddy brown. Begin with equal parts of each color and adjust to remove or add undertones.

Tips for Mixing Grey Paint:

  • Start Small: Always start with small amounts of paint and gradually add more of the darker color until you achieve the desired shade.
  • Mix Thoroughly: Ensure the paint is mixed thoroughly to avoid streaks or uneven color distribution.
  • Consider Undertones: Be aware that different blacks (e.g., ivory black, mars black) can have different undertones (e.g., warm, cool), which will affect the final grey color. Similarly, using different shades of your complementary colors will influence the grey.
  • Test the Color: Before applying the paint to your final surface, test it on a scrap piece of paper or canvas to ensure it is the desired color. Colors can appear different when dry compared to when they are wet.

By experimenting with these methods and adjusting the color ratios, you can create a wide range of grey shades to suit your artistic needs.
