A woman who was ordered to repaint her door or face a fine of up to £20,000 is now facing a new probe thanks to the colour.
Miranda Dickson, 48, has repainted her door after the council told her she wasn't allowed to have it pink. She first painted it green - which planning officers rejected - and now says it is off-white.
Now Edinburgh Council says it has received a complaint, complaining the off-white colour is actually another shade of pink.
Miranda told the BBC: "I am speechless that someone has complained about this colour as far as I was concerned this chapter in my life was closed. I'm shocked and distraught about it. It is definitely not the same colour as it was originally painted - it's an off-white.
"I feel bullied and that it has now become personal."
The council first issued Miranda with an enforcement notice last year, ordering her to change the colour of her door because her home is in a World Heritage Site.
She painted it green just before the deadline that could have seen her fined £20,000 - and when the council said that was not allowed she painted it 'off-white'.
Miranda moved back to the Uk two years ago after living in the USA for nine years and has been renovating her parents' old home.
She said: "It's not like my door is in a bad condition. It costs a lot of money to have the front door painted because they are very large. It's not a quick job.
"The council needs to act with more clarity over paint colour."
A City of Edinburgh Council spokeswoman said: "We have received a complaint alleging that the door has been repainted pink. We're currently looking into this and so can't say more at this time."
Mirance previously said her street, Drummond Place, is popping with brightly coloured front doors, and compared it to Notting Hill or Bristol.
Miranda said: "There's cities in the UK like Bristol, Notting Hill and Harrogate which are brightly coloured.
"Coming home and seeing my front door gives me joy, I'm proud of it.
"It's my house, I own it.
"It's not like I wanted to build a glass box.
"Georgians loved pink - in that era all the windows were painted grey or black, and people had different coloured front doors.
"I've had overwhelming support from people saying 'it's amazing', and 'it makes me smile'."
