Common Paint Matching Mistakes and How to Avoid Them

In commercial vehicle repairs, achieving the perfect colour match is crucial. However, many repairers frequently encounter paint matching mistakes that can compromise their work. Understanding these pitfalls and implementing effective solutions can enhance repair quality.

Common Mistakes

• Relying solely on manual colour matching methods: Technicians often depend on visual assessments without utilising tools like spectrophotometers, leading to overlooked variations.
• Neglecting surface preparation: Proper surface preparation is foundational. Poor preparation can hinder paint adhesion and lead to inconsistencies.
• Incorrect paint code identification: Failing to verify OEM colour formulas using the vehicle ID plate or owner’s manual increases mismatch risks.
• Poor lighting conditions during colour assessment: Metamerism occurs when paint matches under artificial lighting but not in natural light.
• Inadequate paint mixing: Even with the correct code, inconsistent mixing can produce varying shades.
• Insufficient technician training: Technicians lacking training may struggle with blending techniques.

Solutions

• Utilise digital colour matching technology: Invest in tools like spectrophotometers for accurate analysis.
• Conduct spray test panels: Test paint on panels first under various lighting conditions to prevent metameric issues.
• Implement advanced blending techniques: Feathering new paint into existing areas ensures seamless blending.
• Invest time in technician training: Enhancing skills in colour matching can improve repair outcomes.
• Follow OEM repair processes: Adhering to these protocols ensures consistency.
• Conduct regular quality checks: Monitor paint application and colour consistency for improvement areas.

Common Paint Matching Mistakes and How to Avoid Them

Common paint matching mistake	What goes wrong in practice	Why it causes mismatch	How to avoid it
Relying only on the paint code	Painter mixes the formula from the code and goes straight to the panel.	Many colours have multiple variants and batch differences, so one code can have several shades.​	Always check available variants and do a spray‑out card, then compare to the vehicle before painting.​
Not accounting for fade and weathering	New paint is matched to the original formula, not the aged vehicle colour.	UV and weather change the colour over time, so fresh formula looks too bright or clean next to old paint.​	Visually compare and, if needed, tint towards the aged shade and blend into adjacent panels.​
Poor mixing and inaccurate ratios	Toners not fully stirred, scales rushed, thinners added “by eye”.	Incorrect pigment balance and viscosity alter shade, flop and coverage.​	Use calibrated scales, stir toners thoroughly and follow mix ratios exactly every time.​
Ignoring lighting and metamerism	Colour is checked only under one workshop light source.	A colour that matches under one light can shift and mis-match under daylight or other lighting.​	Inspect spray‑outs and panels under multiple light sources and angles before sign‑off.​
Wrong gun setup and application technique	Different pressure, distance or overlaps from the test panel to the vehicle.	Application affects how metallics/pearls lay, changing darkness, flop and effect.​	Keep gun setup, distance, speed and overlap consistent between spray‑out and repair area.​
Skipping spray‑out cards or test panels	Colour is judged only in the mixing cup or on the stir stick.	Wet paint in the pot never looks like the final dried film on a panel.​	Always do a spray‑out, fully dry it, then compare next to the vehicle in good light.​
Trying to “panel‑match” without blending	Painter stops colour right at the edge of the repaired panel.	Even a good match shows a visible step where new and old paint meet.​	Blend basecoat into adjacent panels and clear beyond the repair to hide minor shade differences.​
Tinting with random or unapproved toners	Extra toners are added that are not part of the formula or system.	Unsystematic tinting can fix one angle but ruin another, increasing metamerism and inconsistency.​	Use only toners specified in the mixing system and record small, controlled tint adjustments.

Common Misconceptions About RAL and BS Standards

Several misconceptions about RAL and BS paint standards can confuse commercial vehicle repairers, car garages, and individuals. Understanding these can improve paint choice decisions and help avoid errors.

One prevalent misunderstanding is that RAL and BS standards are interchangeable. RAL, established in Germany in 1927, is a European colour matching system, whereas British Standards (BS) refers to UK-specific standards like BS 4800 and BS 381C. These standards serve different purposes and lack direct equivalence.

Another myth is that RAL is replacing BS standards in the UK. While RAL has gained traction, BS standards remain favoured among UK professionals, especially in construction and architectural applications.

It’s also mistakenly believed that every paint colour has a direct RAL equivalent. Specific shades like Chartwell Green often lack a corresponding RAL code. Knowing which colours do not correspond can save time and ensure accuracy.

Moreover, it is assumed that RAL colours match perfectly across manufacturers. Variations can arise due to production tolerances, especially for metallic shades. Referencing official colour charts ensures precise matches.

Debunking Myths About RAL and BS Standards

The Future of Colour Standards in the Commercial Vehicle Industry

As the commercial vehicle industry evolves, vehicle colour standards are increasingly influenced by market trends, consumer preferences, and technological advancements. Presently, neutral shades dominate this sector, offering practicality and resale value.

Recent data from the Society of Motor Manufacturers and Traders (SMMT) highlights that grey has been the most popular vehicle colour in the UK for several years. Notably, green vehicles have surged due to the growing interest in electrification, suggesting a shift toward more expressive palettes. Manufacturers respond to changing demands, especially for electric vehicles with snappier colours.

Looking ahead, while neutral colours will continue to dominate, there is likely a gradual shift towards more metallic and pearlescent finishes. These trends reflect individual preferences and align with sustainability initiatives.

However, regulatory changes in UK vehicle colour standards have not been forecasted, meaning industry evolution will largely be consumer-driven. This reflects ongoing cultural shifts and technological innovations.
