The flag of Scotland (; , also known as St Andrew's Cross or the Saltire) is the national flag of Scotland, which consists of a white saltire over a blue field. The Saltire, rather than the Royal Standard of Scotland, is the correct flag for all private individuals and corporate bodies to fly. It is also, where possible, flown from Scottish Government buildings every day from 8:00 am until sunset, with certain exceptions.
Use of the flag is first recorded with the illustration of a heraldic flag in Sir David Lyndsay of the Mount's Register of Scottish Arms, . It is possible that this is based on a precedent of the late 15th century, the use of a white saltire in the canton of a blue flag reputedly made by Queen Margaret, wife of James III (1451âÂÂ1488). It is considered to be the oldest flag in Europe.
The heraldic term for an X-shaped cross is a 'saltire', from the old French word or (itself derived from the Latin ), a word for both a type of stile constructed from two cross pieces and a type of cross-shaped stirrup-cord. In heraldic language, the Scottish flag may be blazoned azure, a saltire argent. The tincture of the Saltire can appear as either silver (argent) or white. However, the term azure does not refer to a particular shade of blue.
Throughout the history of fabric production natural dyes have been used to apply a form of colour, with dyes from plants, including indigo and woad, having dozens of compounds whose proportions may vary according to soil type and climate; therefore giving rise to variations in shade. In the case of the Saltire, variations in shades of blue have resulted in the background of the flag ranging from sky blue to navy blue. When incorporated as part of the Union Flag during the 17th century, the dark blue applied to Union Flags destined for maritime use was possibly selected on the basis of the durability of darker dyes, with this dark blue shade eventually becoming standard on Union Flags both at sea and on land. Some flag manufacturers selected the same navy blue colour trend of the Union Flag for the Saltire itself, leading to a variety of shades of blue being depicted on the flag of Scotland.
These variations in shade eventually led to calls to standardise the colour of Scotland's national flag, and in 2003 a committee of the Scottish Parliament met to examine a petition that the Scottish Executive adopt the Pantone 300 colour as a standard (this blue is of a lighter shade than the Pantone 280 of the Union Flag). Having taken advice from a number of sources, including the office of the Lord Lyon King of Arms, the committee recommended that the optimum shade of blue for the Saltire be Pantone 300. Recent versions of the Saltire have therefore largely converged on this official recommendation (Pantone 300 is #005EB8 as a web colour).
The flag proportions are not fixed but 3:5 is most commonly used, as with other flags of the countries of the United Kingdom (flag manufacturers themselves may adopt alternative ratios, including 1:2 or 2:3). Lord Lyon King of Arms states that 4:5 is suitable. The ratio of the width of the bars of the saltire in relation to the width of the field is specified in heraldry in relation to shield width rather than flag width. However, this ratio, though not rigid, is specified as one-third to one-fifth of the width of the field.
The flag of the Church of Scotland is the flag of Scotland defaced with the burning bush.
Several flags outside of the United Kingdom are based on the Scottish saltire. In Canada, an inverse representation of the flag (i.e. a blue saltire on a white field), combined with the shield from the royal arms of the Kingdom of Scotland, forms the modern flag of the province of Nova Scotia. Nova Scotia (Latin for "New Scotland") was the first colonial venture of the Kingdom of Scotland in the Americas. By contrast, the saltire logo of St. Andrew's First Aid is red on white rather than white on blue, in alteration of the Red Cross. Also, the Colombian department of the Archipelago of San Andrés, Providencia and Santa Catalina uses a pale-blue version because the name of principal island (San Andrés, Saint Andrew), though also by the first settlers from Scottish origin.
The Dutch municipality of Sint-Oedenrode, named after the Scottish princess Saint Oda, uses a version of the flag of Scotland, defaced with a gold castle having on both sides a battlement.
The Royal Standard of Scotland, also known as the Banner of the King of Scots or more commonly the Lion Rampant of Scotland, is the Scottish Royal Banner of Arms. Used historically by the King of Scots, the Royal Standard of Scotland differs from Scotland's national flag, the Saltire, in that its correct use is restricted by an Act of the Parliament of Scotland to only a few Great Officers of State who officially represent The Sovereign in Scotland. However, a 1934 Royal Warrant for George V's silver jubilee which authorised waving of hand-held versions continues to be relied upon by fans at sports events and other public occasions. It is also used in an official capacity at Royal residences in Scotland when the Sovereign is not present.
In 2017, the Unicode Consortium approved emoji support for the flag of Scotland, alongside the flags of England and Wales, in Unicode version 10.0 and Emoji version 5.0. This was following a proposal from Jeremy Burge of Emojipedia and Owen Williams of BBC Wales in March 2016,
