To create robin's egg blue, mix a blue pigment such as phthalo blue with a yellow such as cadmium yellow to create a deep cyan. Add titanium white or zinc white to lighten the color and a diluting medium, such as an acrylic paint thinner or linseed oil, to create the desired saturation and consistency. Have an appropriate-sized container, several different sizes of measure and a wooden stick on hand for mixing the paint.Continue Reading
Mix approximately one part yellow to two parts blue. Stir thoroughly and assess the color. If it is too blue for your taste, add a small amount of yellow. If it is too green, add a small amount of blue. Continue adding small amounts of color, mixing thoroughly after each addition, until you have the desired color.
Mixing two intense pigments typically creates a very dark color, so lighten it by adding white to the mixture. Add small amounts of white at a time, mixing thoroughly after each addition until you have lightened the color sufficiently.
Use a commercial acrylic or latex polymer to dilute the paint to the desired consistency and color intensity. Use water very sparingly; too much water added to either acrylic or latex paints causes them to break down. If you are working with oil paints, dilute them with linseed oil.
