Saint Patrick Blue

Saint Patrick Blue is a name that is often mistakenly applied to various shades of blue associated with Ireland.

The official color of Ireland in heraldic terms is azure blue, which is a bright, medium blue.

The color blue's association with Saint Patrick dates from the 1780s, when it was adopted as the color of the Anglo-Irish Order of St Patrick, the senior order of chivalry in the Kingdom of Ireland.

The Order used a sky blue color for its honors, such as the mantle, riband, hat, and badge.

The name St Patrick's Blue was common but never officially used by the Order.

The exact shade of blue used by the Order varied over time, and sometimes had a greenish tint.

Saint Patrick Blue is not a well-defined color, and different sources may give different values for its hue, saturation, and lightness.

One possible representation of Saint Patrick Blue is the hexadecimal color code #23297A, which has RGB values of R:35, G:41, B:122 and CMYK values of C:71, M:66, Y:0, K:52.

This color has a hue angle of 235.9 degrees, a saturation of 55.4%, and a lightness of 30.8%.

Saint Patrick Blue is not widely used as a symbol of Ireland today, as green has become the de facto national color of Ireland, representing the island in many sporting, cultural, and business events.

However, Saint Patrick Blue is still found in some symbols of both the state and the island, such as the coat of arms of Ireland, the flag of the President of Ireland, the badge of the Garda Síochána (the Irish police force), and the logo of the University College Dublin.
