Mixing Acrylic Paint For Rock Art
Mixing acrylic paints to create new colors is one of the necessary skills for creating stunning and vibrant rock art using acrylic paint. While this article is focused on rocks and stones, this skill can be applied to other painting surfaces as well.
In this section, we will get our brushes dirty and practice the basics of color theory. We will do this by making our own color wheel palette, which will be our base to explore other aspects of colors.
After that, we will play with value, saturation, opacity, and other aspects of acrylic paint colors.
How To Mix Acrylic Paint: Color Wheel Palette Tutorial
To make the color wheel palette, we will start by using primary colors and combining them to create secondary, and then use them to create tertiary colors.
Materials:
- Acrylic paint(blue, red, yellow)(white & black)
- Regular palette or wet palette
- Brush
- Painting knife (optional)
- Jar of water and a rag
- Mist Spray (optional)
Steps:
1. Use Primary Colors.
Start by placing a blob of each primary color(blue, red, & yellow) spaced out evenly. Beside each blob put 2 dots of the same colors, these will be used to create tertiary colors later.
Leave space for secondary colors in between each set of primaries.
*Make sure to always clean the knife between each color.
2. Create secondary colors.
Use the spaces between each of the primary colors to combine each of the 2 colors adjacent primary colors.
- Red + blue = violet
- Blue + yellow = green
- Yellow + red = orange
3. Create tertiary colors.
Add a bit of secondary color to the dots of the primary color beside them.
- Red + Violet = Red-violet
- Blue + Violet = Blue-violet
- Blue + Green = Blue-green
- Yellow + Green = Yellow-green
- Yellow + Orange = Yellow-orange
- Red + Orange = Red-orange
Now we’ve created the secondary and tertiary colors, we can begin to experiment with values, saturation, opacity, and other aspects of color. My article “Basic Color Theory” discusses these and the color wheel in more detail.
Adding more white to a color creates a lighter tint while adding black creates a darker shade. And by mixing in small amounts of complementary colors, you can create unique and unexpected variations.
Don’t be afraid to experiment and play around with different color combinations. Mixing and blending paint is a fun and creative process, and there are endless possibilities for creating new and exciting colors for your rock paintings.
In the next section, we’ll explore different blending techniques to help you create smooth and seamless transitions between colors. Feel free to use the paint you just mixed. You can spray or mist it with water to keep it wet.
Blending Acrylic Paint
Now that we’ve mixed up some beautiful colors, it’s time to start blending them together on our rock.
Blending acrylic paint can be challenging since it tends to dry faster than other mediums( like oil).
While there are several blending techniques, we will focus on the very basic one in this section. Gradient blending is the process of smoothly transitioning from one color to another, creating a seamless and beautiful effect. We will use this a lot for our rock painting projects.
How to Blend Acrylic Paint on Rocks: Basic Gradient
1. Apply the first color from one end, to the middle.
Using a flat brush, apply the first paint color on one end of the rock. Brush it from side to side until you reach the middle.
In the gradient rock above, I started by applying red paint from the top to the middle of the rock.
2. Apply the next color from the opposite end, to the middle.
Add the next color to the other end of the rock. Apply it by brushing from side to side until you reach the middle.
Using a clean brush I applied the yellow paint from the bottom of the rock.
3. Blend two colors.
Let the colors meet in the middle and gradually blend with the flat brush creating a smooth gradient. Add more paint if necessary.
Using the same brush, I blend the red and orange until I achieve a gradient effect.
Tips
- Since acrylics dry fast, It helps to prepare all materials and plan what you will paint before putting any paint in your palette.
- Use a DIY or store-bought ‘stay-wet palette’ to keep your paint wet longer.
- Be careful not to add too much water. Adding more paint is better if you like smoother brush stroke flow.
- Use a light touch. Apply the paint lightly and gradually build up the color intensity, rather than trying to apply too much paint at once.
- Make sure to clean your brush thoroughly between each color to avoid muddying the colors together.
- Using a makeup sponge instead of a brush can make blending easier.
- The natural texture and surface of the rock can be rough and uneven. This could add some extra challenges. In my article on how to prepare rocks for painting, I discussed these and their solutions.
With these techniques and tips in mind, you can create beautiful blends and transitions between colors in your rock paintings. In the next section, we’ll explore fun effects that can be created using different blending techniques.
More Blending Techniques: Creating Different Effects
Now that we’ve got the basics of color mixing and blending, it’s time to take our rock painting to the next level by creating unique and creative effects. There are other different blending techniques to do that, let’s explore some of them.
Below is a YouTube video (by Jennifer Funnell ) of acrylic techniques done on paper. Since I got some paint left in my palette, I decided to try all the blending techniques there on my unprimed stones. Later, I’ll show and tell later what worked for me.
These are the fancy blending techniques that I’ve tried and worked for my rocks(which I didn’t have time to prime).
1. Splattering
Acrylic paint splattering is a technique of applying paint to a surface by flicking, splashing, or dripping it onto the canvas with a brush, toothbrush, or other tools. It creates a unique and dynamic effect, often used in abstract or contemporary art.
2. Marbling
The marbling effect involves creating a swirled or mottled pattern on the surface of the rock. This effect can be achieved by dropping different paint colors onto the surface of the rock and then swirling them with a toothpick or skewer.
3. Sgraffito/Scratch Art
Sgraffito is a technique used in art to scratch through a top layer of paint or plaster to reveal a contrasting layer underneath. It allows for intricate designs and patterns to be created with a simple tool, such as a pointed stick or knife.
4. Stippling
Stippling is a technique used in art to create texture or shading by stamping small dots or specks of acrylic paint using the tip of a brush or sponge. By varying the density and size of the specks, artists can create a range of effects, from subtle shading to a highly textured surface.
5. One Brush Stroke
Double load is a painting technique where an artist loads two different colors onto one brush to create a gradient effect. It’s commonly used in decorative painting, like for floral designs and shading, and requires a steady hand and a good eye for color.
This one takes a bit of practice and a good flat brush. Once you get the hang of it, it will make blending colors on small details so much easier.
Note:
If you have more time and paint in your palette, feel free to try all of the techniques in the video. I suggest priming your rock before you start.
Final Thoughts
Always keep in mind the basics of color theory, mixing paints, and blending techniques, as they are the foundation for your rock painting skills. With practice, you’ll be able to create a wide variety of effects and textures, from simple gradients to intricate marbling.
As you continue your rock painting journey, remember to have fun and let your creativity flow. Don’t be afraid to try new things and push the boundaries of what you thought was possible. After all, some of the most beautiful creations come from taking risks and thinking outside the box.
