Every day they plod up and down streets delivering letters and parcels to our homes so your local postal worker probably knows a thing or two about front door designs.
But one postie has gone down a storm on Facebook with his cheeky paint advice for one householder, reports PlymouthLive.
The Royal Mail has posted two photos on the social media site – one showing a black front door with patches of colour samples paints on it while the other shows a useful note that was put through the door by a postie.
It reads: “Second green up from the bottom of the door looks best.”
The post has been liked more than 5,000 times, with the Royal Mail saying: “When you are struggling to choose a colour for your front door… your local postie will help you out!”
Many people commenting on the FB post agreed with postie’s choice, with one saying: “The posties see hundreds and thousands of doors, they know best.”
Another wrote: “I think Mr Postie should have a say as he/she has to look at the door everyday”
So, if you’re after some exterior design advice, you might want to ask your postie for some top tips!
