Flag construction Size Under Finnish law, the ratio of the flag is 11:18 (height:width), very close to the
golden ratio. The swallow-tailed state flag is one unit longer, and the tails are five units long. The cusp width of the blue cross is three units of measure, giving a ratio set of 4:3:4 (vertical) and 5:3:10 (horizontal). When flown from a flagpole, the flag is recommended to have a width equalling one-sixth of the height of the pole.
Usage on
Senate Square, Helsinki, seen flying the State flag at
half-mast, due to the death of President Ahtisaari. The Finnish flag is used in three main variants. The usual national flag is used by all citizens, organisations and Finnish
municipalities and
regions. Anyone is allowed to fly the national flag whenever it is deemed to be suitable. The rectangular state flag is used by bodies of the Finnish national and provincial governments, by the
cathedral chapters of the two national churches (
Evangelical Lutheran and
Orthodox) and non-naval vessels of the state. The swallow-tailed national flag, which is also the naval ensign, is flown by the
Finnish Defence Forces. The presidential standard and the command signs of the
minister of defence,
chief of defence, and commander of the
Finnish Navy are flown only by the respective persons. All public bodies as well as most private citizens and corporations fly the flag on official
flag flying days. In addition to the official flag flying days, there are about ten unofficial but generally observed flag flying days. Besides flag flying days, normally, no flags or corporate flags are flown. Flag Day is celebrated on Midsummer's Day. The Finnish flag is raised at 8 am and lowered at sunset, however not later than 9 pm. On
Independence Day, the flag is flown until 8 pm, regardless of the dark. On the occasion of great national tragedies, the
Ministry of The Interior may recommend flying the flag at
half-mast throughout the country. As a special custom in Finland, the flag is flown at
Midsummer from 6 pm of Midsummer eve until 9 pm of Midsummer's day. This is done to symbolize the fact that the darkness does not come to any part of Finland during Midsummer's Night. Midsummer is also celebrated as the day of the Finnish flag.
Colours The current standard colours were defined in 1995 in both
CIE 1931 and
CIE 1976 standards, with approximate equivalents in the
Natural Colour System (Swedish standard ) and by the
Pantone Color Matching System also given: Meanwhile, the original colors of the Finnish flag are as follows: ,
Canberra. There is no official RGB version of the colours, and in fact the yellow as defined in the CIE L*a*b* standard lies outside
colour gamut of the sRGB colour space. The CIE L*a*b* colours can be approximated in
sRGB (range 0–255) by: blue R=24, G=68, B=126, red R=181, G=28, B=49 and yellow R=237, G=167, B=0. The blue colour is called "sea blue", which is a dark to medium blue. It is not very dark navy blue, and not any bright or greenish shade such as turquoise or
cyan. Red and yellow are used in the coat of arms that appears on the state flag. ==Other rules==
