This is a common issue for many paint by numbers enthusiasts, but the good news is there are simple and effective ways to handle it and get back to enjoying your painting journey.
Setting up your painting area thoughtfully, including arranging your furniture and lighting, can create a comfortable and functional space for your paint by numbers projects, helping you focus better on color application and blending.

If your paint by numbers kit colors don’t match the guide or reference image, don’t worry—this can happen even with popular kits like the Paris Travel Poster Paint by Numbers Kit. The key is learning how to adjust and blend colors to create a cohesive look.
Imagine sitting comfortably with your brush in hand, ready to bring your latest paint by numbers kit to life, only to find that the blue provided doesn’t quite match the sky in your scene. Frustrating, right? Mismatches like these can interrupt your artistic flow. Fortunately, blending techniques and slight color adjustments can minimize visible transitions, making your painting appear more unified. Basically, blending or feathering touch-up paint means softly merging the edges of mismatched paint areas so the transition looks seamless. We’ve gathered practical tips and techniques to help you restore harmony to your palette and keep your creative momentum going.
Identifying the Problem
Before fixing a mismatched color, it’s important to understand why it happened. Sometimes, manufacturing inconsistencies cause paint colors in kits to differ slightly from the intended shades. Other times, mixing errors or variations in batch production can lead to differences. Lighting conditions also influence how colors appear; colors can look one way under indoor lighting but shift outdoors or under natural light.
Paint colors in kits can also change subtly over time due to aging or exposure to air, affecting their appearance when you start your project. Paint that has been sitting for a long time may have a lower water content, affecting its color and sheen. This phenomenon, known as metamerism, means colors that look identical under one light source may appear different under another.
Watch for early signs of mismatches, such as colors looking off when applied or drying differently than expected. Spotting these issues early can save frustration later.
Understanding these causes helps you choose the right approach to fix mismatched paint colors in your paint by numbers kit. If needed, you can take a small paint sample to a paint store for professional color matching using a spectrophotometer, which can create an exact formula to adjust your paints for the most seamless touch-up.
Causes of Color Discrepancy in Paint by Numbers Kits
Several factors contribute to color discrepancies in paint by numbers kits:
- Aging and Fading: Even kit paints can fade or change slightly over time, especially if exposed to sunlight or air. Wear and tear from prolonged exposure can also degrade the paint and alter its appearance.
- Batch Variations: Different production batches may have subtle differences in hue.
- Application Technique: Using a brush differently or varying the paint thickness can alter the appearance. You may need to adjust the shade by making it lighter or darker to better match the desired color.
- Lighting Conditions: Colors may look different depending on whether you’re painting under natural light, artificial light, or in shadow.
- Paint Consistency: Paint that has thickened or dried slightly in the kit can affect color and texture.
Over time, sunlight and dirt gradually change the shade of the paint, making it look different from its original color. This natural process can lead to mismatched paint even if the same color was used initially.
Recognizing these factors helps you anticipate and address mismatches effectively.
Understanding Old Paint and New Paint Differences in Kits
When working on a paint by numbers project, you might notice some colors don’t blend seamlessly, even if they come from the same kit. This can happen due to slight color shifts in the paints after opening or differences in drying times and sheen.
Note: Paint starts to fade fairly immediately once it goes on the walls of your home, which can make it challenging to achieve a perfect match when touching up mismatched paint.
Testing small patches on the canvas and allowing them to dry fully before proceeding can help you evaluate how well colors match. Observing your painting under different lighting conditions ensures you catch any mismatches early. The age of the paint on the wall can affect how well touch-ups match the original color.
If you find a color that’s off, consider mixing it with adjacent colors or adjusting the shade by adding small amounts of white or other colors to achieve a better match.
Preparing for Corrections in Paint by Numbers Kits
Cleaning the wall before painting can help reduce paint match issues due to dirt build-up.
Proper preparation makes correcting mismatched colors easier. Clean your brushes and palette area to avoid contaminating colors. Use a clean, dry brush for blending and avoid overloading paint. If you need to thin the paint, be careful when adding water to avoid overly thinning it, which can affect the paint's consistency for touch-up work or repainting. Before painting, lightly sand the area to remove high spots or glossy finishes that prevent new paint from sticking.
Techniques like feathering—lightly blending the edges of one color into another—help create smooth transitions. Using the same brush strokes and pressure throughout your painting maintains consistency.
If you’re unsure about your color match, consult the paint by numbers kit instructions or reach out to the supplier for advice on color corrections.
Working with Various Paint Colors in Paint by Numbers Kits
Matching paint colors in paint by numbers kits can sometimes feel like a puzzle, especially when you’re working with both old paint and new paint. The challenge often comes down to how the new paint interacts with the surrounding paint on your wall or canvas. Even a slight difference in shade can make a mismatched color stand out, disrupting the harmony of your project.
One of the best ways to achieve a perfect match is to pay close attention to the existing paint and how it looks in your specific space. The surrounding paint can influence the appearance of the new paint, making it look lighter, darker, or even a different hue depending on the lighting and wall color. This is why it’s important to consider the entire wall or area you’re working on, not just the small section you’re touching up.
If you’re struggling to find the right shade, a visit to your local paint store can make all the difference. Paint store professionals are skilled at matching paints and can help you find the closest possible color match. Bringing a small sample of the old paint or a chip from the wall can help the store staff create a custom blend that matches your original paint. They can also offer advice on how to blend the new paint with the surrounding paint for a seamless finish.
When working on your paint by numbers kit, take the time to test your chosen paint colors in a discreet spot before applying them to a larger area. This way, you can see how the new paint interacts with the surrounding paint and make adjustments as needed. With a bit of patience and the right guidance from your paint store, you’ll be able to achieve a flawless color match and avoid the frustration of a mismatched color in your finished piece.
Simple Fixes for Minor Mismatches
For minor mismatches in paint by numbers kits, you can apply paint using different methods to achieve the best results. When performing paint touch ups or minor touch ups, the way you apply paint can make a big difference in blending and texture. Try these quick fixes:
- Mix Basic Colors: Adjust the hue by mixing in small amounts of complementary colors or white to lighten shades.
- Add a Drop of Water: If your paint has been sitting for a while, carefully add a drop of water to old paint—this can help it match better with the surrounding paint.
- Use a Mini Roller: Using a mini roller is usually the best option for touch-ups, as it helps minimize texture differences between the original paint and the touch-up.
- Test Small Areas: Before applying broadly, test color tweaks on a small section of the canvas.
- Use Color Correction Tools: A color wheel or chart can guide you in mixing colors effectively.
Remember to stir paints thoroughly before use to ensure pigments are evenly distributed—the “good stuff” often settles at the bottom.
Techniques for Major Mismatches
When color mismatches are more pronounced, choosing the right method is crucial for achieving a seamless result with your wall paint. Consider these approaches:
- Layering: Apply multiple thin coats to cover the mismatched area and build up the correct color gradually.
- Base Coats: Use a neutral base coat (like white or beige) under problematic areas to neutralize unwanted hues before applying the final wall paint.
- Repainting Sections: For large mismatched areas, repaint the whole wall from corner to corner to ensure even coverage and blend the new paint with the rest of the surface. Covering larger areas with the appropriate applicator, such as a roller, helps achieve a uniform finish. Repainting the entire wall is often the best solution for mismatched paint.
- Custom Mixing: Combine paints from your kit or add artist-grade pigments to fine-tune colors and match the rest of the wall.
- Feathering and Blending: Feather the new paint out from the repaired spot or paint the entire wall section for seamless blending. When performing touch-ups, feather the edges by using light, overlapping strokes to blend the new paint gradually into the old and achieve a smooth transition with the rest of the wall.

The applicator used to apply paint to a wall has everything to do with the uniformity of appearance, so choose your tools carefully for the best results.
Matching the sheen (flat, eggshell, satin, etc.) is as critical as matching the color, since a mismatch in gloss will be highly visible.
Always test your adjustments on a small area first to avoid unintended results.
Common Mistakes to Avoid with Paint by Numbers Kits
Avoid these pitfalls to ensure better color matching and achieve a precise, professional paint touch-up job:
- Skipping Paint Stirring: Not mixing paint well can lead to uneven color.
- Using Different Brushes or Techniques: Changing application methods alters texture and appearance.
- Ignoring Sheen Differences: Variations in paint finish can make colors stand out.
- Applying Paint to Small, Isolated Spots: This can create visible patches; instead, blend and feather edges.
- Not Testing Colors: Always test paint on a small area before full application.
- Painting Trim Carelessly: Take extra care when painting trim to avoid mistakes and ensure a clean, sharp finish.
- Using a Fresh Paint Sample: If you picked up a fresh sample of paint for your touch-up job, be aware it may have a slightly different mix than the original paint on your walls, leading to mismatched paint.
Preventing Future Mismatches in Paint by Numbers Kits
To keep your paint by numbers colors consistent:
- Organize and Label Paints: Keep your paints well-organized to avoid confusion.
- Store Paints Properly: Seal paint pots tightly and store in a cool, dry place to preserve color integrity.
- Test Colors Before Use: Try colors on a scrap piece or corner of your canvas.
- Invest in Quality Kits: Higher-quality kits often provide more consistent and reliable paints.
- Maintain Consistent Lighting: Paint under similar lighting conditions in each room to reduce color perception shifts and ensure color consistency.
- Mix Multiple Cans for Large Projects: If using multiple cans for a large project, mix them together in a single bucket to ensure color uniformity across the whole room.
- Apply Primer Before Repairs: Before painting over a repair, apply a high-quality primer to seal the porous surface and ensure even paint absorption.
- Cabinets: When painting cabinets, especially kitchen cabinets, carefully select your color and ensure consistency for a professional finish.
These practices help ensure your future projects go smoothly with fewer color surprises.
