Choosing the Right Colours for Your Model Kit Masterpieces

When we embark on the journey of assembling our model kits, the selection of colours plays a pivotal role in bringing our miniature masterpieces to life. The colour palette we choose can transform a simple kit model into a striking replica that captures the essence of the original design. It’s essential to consider the historical accuracy, the intended mood of the model, and the overall visual impact. Whether it’s a military aircraft, a classic car, or a fictional spacecraft, the hues we apply are more than mere decoration; they are an expression of creativity and attention to detail.

Understanding colour theory provides us with a strong foundation to make informed choices. Complementary colours can make our models pop, while analogous colours offer a more harmonious look. We must also factor in the importance of shading and highlighting to add depth and realism to our creations. Selecting the right finish – matte, satin, or gloss – further enhances the texture and appearance, ensuring our models stand out.

Equally important is the quality of the paint we use. High-quality paints provide better coverage, more vibrant colours, and a smoother finish. They can significantly influence the end result, accentuating the intricate details of our model kits. By carefully considering each of these elements, we set ourselves up for success, ensuring our kit models are not just displays of our skill, but also a testament to the power of colour in bringing our projects to life.

Fundamentals of Colour Theory

When we approach colour theory, we need to acknowledge that colour choices in model paints profoundly affect the visual impact of our miniature masterpieces. Key considerations include the psychological effects of colours and how different hues relate to one another.

Understanding Colour Psychology

Colour psychology explores how various shades can influence emotions and behaviours. For instance, reds often evoke energy and passion, whereas blues tend to suggest calmness and reliability.

  • Model Paints:
    • Reds - Ideal for areas meant to stand out, like the cockpits on fighter models.

    • Blues - Best for creating a sense of tranquillity, such as skies or bodies of water in dioramas.

Understanding these emotional cues can guide us in selecting colours that match the intended atmosphere of our models.

Colour Wheel and Colour Relationships

The colour wheel is an essential tool showcasing the spectrum of hues and their relationships.

  • Primary Colours: Red, yellow, blue - fundamental colours that can’t be created by a mixture.

  • Secondary Colours: Green, orange, purple - created by mixing primary colours.

  • Tertiary Colours: Yellow-orange, red-orange, red-purple, blue-purple, blue-green, yellow-green - made by mixing a primary and a nearby secondary colour.

Model Paints Application:

  • Complementary Colours: Opposite each other, they offer high contrast. Ideal when we want parts of the model to pop, like highlighting the trim on military models.

  • Analogous Colours: Adjacent to each other, providing a harmonious look. We use these for a gradual variation in the colour of a model's surface.

  • Triadic Colours: Evenly spaced around the wheel, these schemes introduce vibrant diversity to our models while maintaining balance.

Our understanding of these relationships allows us to create visually appealing and coherent colour schemes in our model kits.

Selecting Colours for Your Kit

Before we dive into the specifics of colour selection, realise that the right palette can transform a model kit from mundane to magnificent, enhancing both realism and thematic consistency.

Matching Colours with Kit Themes

When choosing our paints for model kits, we align them with the kit's theme to ensure thematic coherence. Historical models, such as WWII tanks or vintage aircraft, demand a palette that reflects their era, often requiring us to research to find authentic colours.

  • Military Models: Use matte finishes and historically accurate colours; shades of green, grey, and brown are typical.

  • Science Fiction: Metallics, neons, and gloss finishes provide a futuristic feel.

  • Natural Environments: Earth tones, greens, and blues complement landscapes or wildlife subjects.

We should always consider the emotional impact of the colours. Bright colours can convey vibrancy and energy, whereas subdued tones can create a sense of age or realism.

Considering Model Scale and Detail

The scale of our model plays a crucial role in selecting the appropriate colour shades and finishes. Larger scale models can accommodate more nuanced colour variations and details, while smaller scales require a more simplified palette to avoid a cluttered appearance. The detailing we can achieve in different scales is usually as follows:

  • 1:35 or Large Scale: Multiple shades can be used for depth; weathering techniques add realism.

  • 1:72 or Small Scale: Limited range of colours; high-contrast details can be lost, so we use simpler schemes.

For intricate components, we use contrasting but complementary colours to bring out the details. It is essential to balance realism with visibility as smaller models often require boldness for details to stand out. A clear coat finish adds protection to our detailed work and can shift the model’s appearance from matte to satin or gloss, depending on our desired effect.

Application Techniques

Let’s next guide you through achieving the right paint consistency and creating smooth gradients on your model kits using proper layering techniques.

Paint Mixing and Consistency

When we start with model paints, ensuring that they are thoroughly mixed is crucial for uniform colour application. We typically recommend using a stirring tool or mixer for efficient mixing. Consistency is equally important; paints should be neither too thick nor too thin. A consistency similar to skimmed milk is ideal for most airbrush applications, while brush painting might require a slightly thicker mix.

Here's a quick reference table for ratios:

Paint Type




Water or Acrylic Medium



White Spirit or Enamel Thinner



Lacquer Thinner


Note: Ratios can vary based on the brand and desired effect.

Layering and Gradients

For layering, we use a methodical approach to build colour depth and gradation. Begin with a base coat and allow it to dry completely before applying subsequent layers. It is vital to apply each layer thinly to avoid texture buildup. For gradients, we use a feathering technique where the paint is gradually thinned and blended into the base colour, working while the paint is still wet for smoother transitions.

Here are the steps we should follow:

  1. Apply the base coat and wait for it to dry.

  2. Place a thin layer of the second colour, overlapping the first.

  3. While still wet, lightly feather the edge of the second colour with a clean, damp brush to blend.

  4. Repeat the process for additional layers, letting each dry before applying the next.

Using these application techniques, we ensure our model kits have a professional and seamless finish.

Maintaining Colour Integrity

We understand the importance of colour fidelity in our model kit masterpieces. To ensure that the vibrant hues and subtleties of our paints remain unaltered over time, we must apply protective treatments and adhere to best practices for long-term preservation.

Protective Coatings

Choosing the Right Varnish: Selecting an appropriate varnish is crucial for protecting the painted surfaces.

  • Matte Varnish: Ideal for hiding small imperfections and reducing glare.

  • Satin Varnish: A middle ground between matte and gloss, offering a subtle sheen.

  • Gloss Varnish: Enhances colour depth and contrast, suitable for models that benefit from a shiny finish.

Application Tips:

  • Ensure the model is free from dust.

  • Apply in thin and even layers.

  • Allow ample drying time between coats.

Long-Term Preservation

To prevent degradation of our paints, we must consider environmental factors and storage conditions.

Environmental Factors:

  • Light Exposure: Keep models out of direct sunlight to prevent fading.

  • Humidity Levels: Aim for a consistent relative humidity, ideally around 50%.

Storage Solutions:

  • Utilise clear display cases that offer UV protection.

  • Include silica gel packets to control moisture levels.

  • Ensure that storage areas are clean, dry, and stable in temperature.

By following these recommendations, we preserve the integrity and appearance of our model kits for years to come.
