The owners of a 17th Century thatched cottage have been ordered to repaint it, because it's too pink.
Ann Kennedy and her husband Mark say their Grade II listed dwelling in Kennford, Devon, is exactly the same colour today as it was when they bought it 12 years ago.
But officials have threatened legal action over the 'unauthorised' hot pink paintwork.
Teignbridge District Council said Ann and Mark did not ask for permission to "alter" a listed building when they carried out the disputed paint job.
Ann and Mark applied retrospectively for planning permission and will find out in June whether they can keep their cottage pink.
A spokeswoman for Teignbridge District Council said: "We advised the owner that Listed Building Consent was required."
So what can you do?
Homeowners generally only need permission for changes that fundamentally alter the building's structure or size, such as an extension. This means you can usually paint the exterior any colour you like without permission.
However, the rules around listed buildings are much stricter. A building becomes listed when its history or architectural importance is considered worth protecting.
It can be changed, and even demolished, but permission from the local authority must be granted first.
Any changes that affect the character or appearance - inside and out - need to get approval before works takes place. This includes painting, replacing doors and windows, extending the building or just changing the fireplace.
“It is important to remember that it is a common misconception that Grade II listing mean you can’t alter the outside but can do what you like on the inside – this is untrue and can lead a buyer into a mine field of hazards.
"It is also a good idea to ask building control and the conservation officer whether they have a list of approved contractors and builders before you start work on your new home," said Nick Hole-Jones, director of Hamptons International Country House Department.

After an application is lodged, anyone with a vested view, including neighbours, can comment on the proposed changes. The council will then decide whether to let work go ahead.
A decision should be made within eight weeks for smaller projects, or 13 for bigger changes.
Carrying out work without permission, as in the case of Ann and Mark Kennedy, is a criminal offence and owners could find they are prosecuted.
The local authority can also insist that the changes are reversed, potentially costing owners lots of wasted time and money.
In some cases, homeowners can get a grant for repairs to listed buildings from English Heritage, Historic Scotland or the Welsh Government.
There are approximately 374,081 listed buildings in England, according to English Heritage, and 90% of these are Grade II listed.
