The Hidden Impact of Colour Accuracy on Body Shop Profitability

How Poor Colour Accuracy Really Hits Margins

Poor colour accuracy drives waste in three critical areas: materials, labour and time. Every incorrect mix or respray increases paint consumption, raises disposal costs and erodes margin. Labour inefficiencies quickly follow, as painters spend valuable time tinting colours, reworking panels or waiting for corrections, while vehicles remain in the booth instead of moving through the workshop.

In a conveyor-belt repair environment, where work passes from technician to technician, one mistake can disrupt the entire process. If colour accuracy isn’t right, jobs stall, rework increases and cycle times suffer.

This is a challenge Fix Auto Chessington recognised early. Like many U.K. body shops, it was seeing how small inaccuracies on the paint line could have a disproportionate impact on productivity and cost control.

Skills Shortages and the Consistency Challenge

The issue is compounded by the industry’s ongoing skills shortage. Many body shops today employ a mix of highly experienced painters who rely on traditional methods alongside technicians who are more open to digital tools. While that diversity brings strengths, it can also introduce inconsistency.

At Fix Auto Chessington, this was particularly evident in colour mixing. Traditional processes often required painters to mix large minimum quantities of paint, even for very small repairs. If the colour wasn’t quite right, that paint would be discarded, wasting both time and money.

“In the past, you could easily end up mixing a large amount of paint, realise it wasn’t right and then throw it all away. That’s time and money straight in the bin,” says Arnold Gauci, Director at Fix Auto Chessington.

Trial-and-error tinting also places pressure on painters and introduces unnecessary variability into the process. In an industry already under strain, relying on manual judgement alone makes consistency harder to achieve.

Reducing Rework with Smarter Colour Systems

Modern colour technology is helping body shops regain control. High-accuracy colour scanning, better variant management and digital colour formulation tools reduce reliance on individual interpretation and guide painters toward the most accurate match the first time. This significantly reduces the need for resprays and spray-out cards, keeping jobs moving and improving overall throughput.

Automation plays a growing role here too. Automated mixing systems remove human error from paint measurement and allow body shops to mix precisely what is required for each repair. This is particularly important as repair profiles evolve, with smaller components, electric vehicles and specialist coatings becoming more common.

At Fix Auto Chessington, the introduction of Sherwin-Williams Collision Core™ Pronto transformed material usage. Instead of being forced into large minimum mixes, the team can now produce very small, highly accurate quantities of paint.

“Being able to mix exactly what we need, with that level of accuracy, has made a huge difference,” explains Gauci. “We’re no longer wasting paint just because of minimum mix requirements.”

The benefits extend beyond cost savings. Reduced waste also supports sustainability objectives, lowering environmental impact while improving profitability. By producing only the paint required for each repair, body shops can significantly cut the volume of leftover material that would otherwise require storage, reuse or disposal as special waste.

Accuracy, Insight and Control

Connected digital tools further strengthen this approach by helping body shops prevent issues before they occur. Integrated alerts, technical guidance and usage data allow painters and managers to make informed decisions, reducing the likelihood of rework and highlighting opportunities for improvement.

For managers, this visibility provides greater control over material consumption, rework trends and cost leakage, turning colour accuracy into a measurable business advantage rather than a reactive problem.

The Value of Ongoing Support

Technology alone, however, is only part of the equation. Ongoing support plays a critical role in ensuring systems deliver long-term value.

For Fix Auto Chessington, this has been a defining factor. “One of our main frustrations in the past was a lack of support,” says Gauci. “With Sherwin-Williams, it’s completely different. If we raise an issue, they come back to us quickly with a solution and a clear plan on how to move forward.”

Regular site visits, proactive technical input and business-level reporting have helped the team stay ahead of potential issues, optimise paint usage and identify further efficiency gains.
