Green to red.
A number of An Post post boxes in Dublin have been painted red and some people are very confused.
These people on Twitter spotted the change earlier.

The post boxes have been painted red ahead of next weekend’s 1916 centenary celebrations.
In the 'did you know' section of the An Post website, it states.
"When Ireland was ruled by Britain, all the post boxes were red just like the ones you see in London. Once Ireland won independence all the post boxes were painted green."
The red boxes display a word and a text number, people can use them to access video clips of what would have been happening in the spot in 1916.
It's part of An Post's GPO Witness History project for 2016.
