This Mixbox tutorial will guide you through everything you need to know to start creating stunning digital paintings with realistic color mixing. Unlike complex Quixel Mixer tutorials that require substantial 3D knowledge, getting started with Mixbox is straightforward.
Unlike Quixel Mixer or Substance Painter that require downloads and installation, Mixbox is browser-based:
rgbatohex.com/tools/mixer-painter-tool in any modern web browserPro Tip: Unlike most Quixel Mixer tutorials that require system specifications checks, Mixbox works on virtually any device with a modern browser. This makes it perfect for beginners or artists using lower-powered devices.
The Mixbox interface is intuitive and streamlined compared to complex tools like Substance Painter:
Similar to Quixel Mixer brushes, Mixbox offers specialized brush types for different artistic effects:
Perfect for precise line work, sketching, and detailed illustrations.
Comparable to the hard surface brushes in Quixel Mixer.
Creates soft, flowing effects with beautiful color diffusion at the edges.
Provides effects similar to Substance Painter's watercolor smart materials but with real-time mixing.
Delivers textured strokes perfect for rough sketching and organic textures.
Comparable to the grunge brushes in Quixel Mixer.
Creates rich, textured strokes with directional brushwork and paint buildup.
Delivers effects similar to premium brushes in Flame Painter.
To select a brush, click the brush icon in the left toolbar and choose your preferred style from the menu. Each brush interacts differently with the canvas and with existing colors, providing a versatile toolkit for different artistic styles.
Mixbox color selection works differently than traditional digital color pickers:
Pro Tip: Unlike Quixel Mixer where you might need to create material layers, in Mixbox you can achieve complex color variations simply by painting one color over another and letting the realistic mixing occur naturally.
Now that you understand the basics, let's explore advanced mixer painting techniques that will elevate your digital artwork to the next level.
Similar to techniques you might learn in a Quixel Mixer tutorial, glazing involves applying thin layers of color to build up richness and depth:
The key difference from traditional digital glazing is that Mixbox color mixing will create realistic interactions between layers, maintaining vibrancy rather than becoming muddy.
Create rich, textured paintings similar to traditional oil painting:
Pro Tip: Unlike standard mixer painting apps, Mixbox's oil brush creates paint buildup effects where colors mix at the edges, similar to premium features in Flame Painter.
Mixbox is exceptional for learning color theory because it behaves like real paint:
While Mixbox doesn't have the extensive brush customization of Substance Painter, you can still create varied effects:
While not as advanced as Quixel Mixer symmetry tools, you can achieve symmetrical designs in Mixbox:
Advanced User Tip: We're currently developing built-in mixer symmetry tools similar to those found in Quixel Mixer. Subscribe to our newsletter to be notified when this feature launches.
Follow these project-based Mixbox tutorial workflows to create professional-quality artwork:
Use the chalk brush with large size to block in sky, mountains, and foreground with basic colors. Focus on composition rather than detail.
Switch to watercolor brush to blend areas where elements meet. Add atmospheric perspective by making distant objects cooler and less saturated.
Use the pen brush for fine details like trees, rocks, and highlights. Add texture with the chalk brush at lower opacity.
Unlike Quixel Mixer painting where you might use material layers, in Mixbox use these color techniques:
Use the watercolor brush with a warm brown tone (Raw Sienna) to establish the basic form and proportions.
Build up skin tones using Mixbox's realistic color mixing. Start with base tones and gradually add reds for warm areas and blues for cool areas.
Use the oil brush for textural details and the pen for fine elements like eyelashes. Add highlights with titanium white at high opacity.
Pro Tip: For realistic skin tones, don't use pure white for highlights. Instead, mix your highlight color with a tiny touch of the complementary color of your base skin tone. This creates a subtle dimension that pure white can't achieve.
Abstract art is where Mixbox color mixing truly shines compared to standard digital tools:
Abstract expressionism benefits greatly from Mixbox's realistic pigment simulation, as the color interactions create natural vibrancy and complexity that would require extensive layering in conventional digital painting software.
Like any professional tool, mastering the Mixbox manual shortcuts will significantly improve your workflow efficiency. These shortcuts are more straightforward than what you'd find in a Quixel Mixer manual:
Mixbox is designed to run in browsers, but you can optimize your experience:
If using a touch screen and experiencing palm rejection problems, try using a stylus or adjusting your hand position to minimize accidental touches.
If the color wheel isn't registering clicks correctly, try switching to the "Paints" tab and back to reset the interface.
If changes to brush size or opacity don't seem to take effect, click on a different brush type and then back to your preferred one to reset the brush properties.
If the download function doesn't work, try a different browser. Some browsers have stricter security settings that may block canvas downloads.
Mixbox Paint Mixer isn't just for creating artwork—it's also an exceptional educational tool for teaching color theory and painting techniques:
Unlike standard digital tools, Mixbox demonstrates genuine color interactions:
Educator Tip: Use Mixbox to demonstrate the difference between additive (RGB) and subtractive (pigment) color models by toggling between Normal and Mixbox modes with the same colors.
Mixbox's browser-based approach makes it ideal for classroom settings:
Have students create their own color wheel using only primary colors, mixing to create secondary and tertiary colors.
Assign students to create the same simple landscape using different color palettes to convey different moods or times of day.
Have students create a grid showcasing different effects achievable with each brush type at different sizes and opacities.
Assign students to recreate a portion of a famous painting, focusing on matching colors through mixing rather than picking them directly.
Yes, Mixbox Paint Mixer is completely free to use without any premium tiers, subscriptions, or hidden costs. Unlike Quixel Mixer, which offers a free version with limitations and requires an Epic Games account, Mixbox is fully featured from the start with no login required.
While Substance Painter is focused on 3D texturing with a comprehensive layer-based workflow, Mixbox specializes in 2D painting with revolutionary color mixing technology. Substance Painter offers more advanced features for 3D workflows, but Mixbox provides more realistic color mixing behavior for traditional digital painting.
Currently, Mixbox doesn't have the built-in mixer symmetry tools that Quixel Mixer offers. However, we are developing this feature for future updates. In the meantime, you can create symmetrical designs by painting one half and using external software to mirror your work.
Unlike Substance Painter or advanced versions of Quixel Mixer brushes, Mixbox doesn't currently support creating custom brushes. However, you can achieve diverse effects by adjusting size, opacity, and combining the existing professional brush types (pen, watercolor, chalk, and oil).
Most online painting tools use simple RGB color mixing, which produces muddy colors when mixing complementaries (e.g., yellow + blue = gray). Mixbox uses advanced pigment simulation technology based on the Kubelka-Munk theory, creating realistic mixing behavior where yellow + blue = green, just like real paint.
While Mixbox doesn't directly integrate with 3D workflows like Substance Painter, you can use it to create texture maps and concept art that can be imported into 3D software. Many artists use Mixbox for concepting color schemes and material appearances before recreating them in 3D tools.
Currently, Mixbox supports basic pressure sensitivity on devices that provide this information to the browser. The support isn't as sophisticated as Substance Painter or desktop applications, but it does respond to pressure for size and opacity on compatible devices.
Currently, Mixbox exports flattened PNG images. Unlike Quixel Mixer or Substance Painter which support layered exports, Mixbox focuses on the direct painting experience rather than post-processing workflows. We recommend saving incremental versions of your work if you need to preserve stages of your process.
