When first introduced for its inaugural season, The Connecticut Sun's original logo featured a bright yellow sunburst behind an orange “CT SUNS” lettering above a white silhouette of two hands holding up four fingers representing unity and strength. This design was slightly modified when it was updated for the 2004-2005 season adding light blue color to represent water while keeping the same font style used before.

In the 2006-2007 season, another change occurred where new colors were added including navy blue which replaced orange from the previous version but kept the overall look intact. Then again after a few years later (2008) another update happened to remove all other colors except navy blue & yellow with the addition of curved lines around the sunburst giving a more modern feel to the logo. Finally, the prior 2012 version saw some minor changes like the removal of curved lines along with a slight change in how hand silhouettes were placed inside the sunburst making them closer together than before.

Today, the current version features just two colors: Navy Blue & Yellow which are also the team's official ones, however, there is still the same concept being followed: A strong unified force represented by four fingers held up by two hands under glowing sunshine symbolizing optimism & hope associated with the CT Sun franchise.
