Yellow has been the traditional UE Santa Coloma color. Manly of the home kits alternate yellow and black. Until 2013 the badge was representing Santa Coloma's pre-romanical church tower and the most traditional team icon, the squirrel.
The nowadays crest still represent the icons of UE Santa Coloma, featuring the club colours (yellow and black) and the year of fundation (1986).
The club have an alternative badge (main crest during the first leg of the 2013-14 season) representing the Santa Coloma's squirrel and the colours of the Andorran nation with the motto's country "Virtus Unita Fortior".
The club's nickname, as seen from the crest, is Esquirols (Squirrels) due to the number of the animals that live around the town of Santa Coloma. There is a long-standing tradition for a number of fans to wear squirrel costumes at the club's last home game of each season.
The local rival of UE Santa Coloma is actually their neighbour's hometown football team FC Santa Coloma. The rivalry between these two teams has increased since the 2009/10 season when those teams were competing for winning the Premier Andorran League.
