The techniques for mixing colors with acrylic brushes are as follows:
First, basic color-matching skills
Understand the three primary colors and secondary colors:
The three primary colors of acrylic painting are red, yellow and blue, and they can be mixed to produce the colors of all pigments.
When two primary colors are mixed, they form secondary colors: red + yellow = orange, red + blue = purple, blue + yellow = green.
Master the method of compound color matching:
Mixing a secondary color with one of the primary colors can form a compound color. For instance, red + purple = purplish red, red + orange = orange-red, red + green = ochre, etc.
Second, advanced techniques for mixing colors
Control the proportion of pigments:
By adjusting the proportions of different colors on the palette, the desired tones and lightness can be obtained.
For example, if you want a warmer orange, you can add more red. If you want a cooler orange, you can add more yellow.
Use white to adjust the depth:
Any acrylic paint can be adjusted in depth after adding white.
The more white is added, the paler the color becomes and the closer it is to white. On the contrary, the darker the color is.
Try gradient colors:
Gradually transitioning between the two colors can create gradient colors, making the picture more natural and harmonious.
Gently sweep between the two colors with a wet brush to create a smooth gradient effect.
Create special effects
By mixing different proportions of colors and adding media (such as acrylic blending liquid, quartz sand, etc.), various special effects can be created, such as frosted texture, luster, etc.
Third, precautions during color mixing
Keep the brush clean:
When mixing colors, it is necessary to clean the brush in time to avoid color mixing, which may affect subsequent color mixing.
Control the consistency of the pigment:
The consistency of acrylic paint will affect the color mixing effect. If the pigment is too thick, an appropriate amount of medium can be added to dilute it. If the pigment is too thin, an appropriate amount of pigment powder can be added to thicken it.
Observe the color of the finished painting:
When adjusting the color, always observe the color of the final painting to ensure that it meets your expectations. You can first mix small patches of color on the palette and then apply them to the canvas to observe the effect.
Avoid excessive mixing:
Be careful not to over-mix the colors to avoid a cloudy effect. You can first mix the general colors on the palette and then make further adjustments on the canvas.
Fourth, practical suggestions
Practice more
Color matching is a skill that requires continuous practice. Through more practice, one can gradually master the skills and methods of color mixing.
Reference color theory:
Understanding color theory is helpful for better mastering color-matching skills. One can read relevant books or online resources to learn the basic principles and matching methods of colors.
Record the color-matching result:
When mixing colors, you can record the result of each color mixing and the proportion of colors used. This can help oneself accumulate color-matching experience and improve color-matching ability.
