Summary

A car's paintwork can hide its past, from minor touch-ups to major accident repairs.
Mismatched paint, overspray or uneven texture are the classic signs of a repaint.
A DVLA-recorded colour change shows on a history check, and a repaint can hint at a past write-off.
A repaint is not always a problem, but it is always worth a question.

A car's colour is more than a cosmetic detail. A change in paint can reveal a lot about a car's history, from a simple respray to a cover-up for accident damage. Knowing how to spot the signs protects you before you buy.

This guide explains why colour changes matter, how to spot a repaint with your own eyes, and what to do if you find one.

Why a Colour Change Can Be a Red Flag

Any inconsistency in paintwork is worth a closer look. There are three main reasons to pay attention.

Accident repairs

If panels look like slightly different shades, the car may have been in a crash and resprayed to hide the damage. A write-off check can reveal whether it was ever declared a total loss.

Cosmetic updates

Sometimes a repaint is purely about a fresh look. Even then, make sure the work was not done to disguise rust or minor damage that could affect the car later.

Resale value

Cars in their original colour tend to hold value better. A non-original paint job, especially one that looks slightly off, can make a car harder to sell and reduce its market value.

Recorded Colour Change vs a Repaint

There are two different things to check, and they are not the same.

A recorded colour change: The keeper told the DVLA the car's colour changed, so the V5C and history record are updated. This is the honest, legal way to do it.
An unrecorded repaint: The car was resprayed but the record was never updated. This is where a repaint can hide a bad past.

A history check shows the recorded colour. If the car in front of you does not match that record, ask why.

How to Spot a Repainted Car

You can catch most repaints with a careful look. Work through these checks.

View it in natural light. Differences in how panels reflect the sun, or in texture, often reveal a respray.
Inspect hidden areas. Open the bonnet, boot and doors. A different shade in these spots is a strong clue.
Check the edges. Look around door frames and seals for overspray or uneven paint, a common giveaway.
Use a paint thickness gauge. This tool highlights extra layers of paint on repaired panels, if you want to dig deeper.
Run a history check. A vehicle history check confirms the recorded colour and flags any past accident markers.

What If the Car Has Been Repainted?

A repaint is not automatically a dealbreaker. It just means you should ask a few more questions.

Talk to the seller. Ask when and why the work was done. An upfront answer is reassuring.
Look for other issues. If the repaint followed a crash, check carefully for structural damage.
Get a mechanic's opinion. A professional can spot problems the eye misses.
Negotiate. If the paintwork affects value, use it to agree a fairer price.

How a Repaint Affects Value and Insurance

A repaint touches more than looks. It can affect what a car is worth and how it is insured, so it pays to understand the impact.

Value

A full, professional respray in the original colour has little effect on value, and can even help a tired car. A partial or poorly matched repaint usually lowers value, because buyers assume it hides a repair.

Insurance

A cosmetic colour change is not usually a problem, but you must tell both the DVLA and your insurer. An undeclared change could complicate a claim. If the repaint followed a write-off, that history stays on record and affects premiums.

In short, honesty is cheap and cover-ups are costly. A recorded, well-documented respray is nothing to fear. It is the hidden ones that carry the risk.

Common Questions

Is it legal to change a car's colour?

Yes, as long as you tell the DVLA so the V5C is updated. Failing to report a colour change can invalidate the logbook.

Does a repaint always mean accident damage?

No. Many repaints are cosmetic. But a partial respray on just one or two panels is more likely to point to a repair.

Will a history check show if a car was resprayed?

It shows the DVLA-recorded colour and any accident or write-off markers. It cannot see an unrecorded respray, which is why a physical inspection still matters.

How can I find a car's original colour?

The V5C logbook records the registered colour, and a history check shows any recorded change. The manufacturer's paint code, often on a sticker in the door shut or under the bonnet, confirms the factory colour.

Does a repaint cause an MOT failure?

No. The MOT does not assess paintwork or colour. It only checks safety and emissions, so a respray has no bearing on whether a car passes.

Paying attention to a detail as small as colour can save you from a big headache. Inspect the paint, match it to the recorded colour, and run a history check before you decide. For the bigger picture, see our guide on how to conduct a vehicle history check.
