Green Cross

St. Lazarus Cross
The Green Cross, a symbol of First Aid...

...but with an environmentally-unfriendly colour
which is also linked to early death.

Some nine hundred years ago a green Greek Cross emblem was used by the Hospitallers of St. Lazarus. Centuries later Islam adopted green as a symbol of nature and life; a common understanding, irrespective of religion.

To represent life in a spiritual sense there is no more suitable colour than green. However, since it is a special colour for Muslims, green crosses are now rarely seen in a Christian context, even in places like Ireland, where green is very much a national colour and Catholicism is the predominant denomination.

Exceptions are seen in the emblems of Baptist churches in Rwanda, who use a green cross in their group logo (AEBR), the restorationist Harpeth Community Church in Franklin, Tennessee, USA (HCC), and also the Reformed Church in America (RCA).

Generally today, a green cross has a secular meaning and the most common use is health care. In particular, the green cross represents First Aid.

Red Cross

The Red Cross of the International Federation of Red Cross and Red Crescent Societies is an emblem protected under the Geneva Conventions Act and cannot be used without permission. Contrary to popular belief, the Red Cross is not a public-domain First Aid symbol.

The green cross is often used by pharmacies. The style of cross is not universal but usually mimics the shortened arms of the Red Cross. Some pharmacies prefer the Bowl of Hygieia and/or the Rod of Asclepius, often green, and may also incorporate a green cross, just for good measure. Green is a fitting colour for a science with its historical use of plant extracts.

Hospitals love green staff uniforms and green wall paint, following the theory that our eyes are most perceptive in detecting the short wavelengths of the colour green, making things easier for the brain and resulting in a calming effect. [...though not for me. Green reminds me of the lawn which needs mowing yet again, making me green with envy of high-rise apartment dwellers.]

The International Standards Organisation recommends that a white cross on green background is used as a First Aid symbol. (See also the emergency services' Star of Life.) A variation is a green cross on a white field. Although this is not recommended by ISO, it is still widely recognised as a first aid symbol.

Democratic Progressive Party of Taiwan
DPP

Green is commonly adopted by environmentalists and in 1986 one such group in Taiwan joined with liberals to form the Democratic Progressive Party (DPP). Their banner is a green outline of Taiwan within a white cross on a green ground. Part of their agenda is anti-Communism and it just so happens that on the opposite side of the colour wheel is red, the predominant colour of the flag of the People's Republic of China.

Green Cross International
GCINT

A few years later another environmental group used the green cross in their emblem; the Green Cross International (GCINT) organisation, founded in 1993 by the former Soviet leader the late Mikhail Gorbachev. This group has branches around the world, though in many countries a green cross symbol has been used by conservation and welfare organisations since much earlier than 1993.

In Germany, for example, is the Deutsches Grünes Kreuz e.V. (German Green Cross) was founded in 1948. It doesn't restrict itself to human health, rather also has concern for the protection of animals and plants.

In Korea is the headquarters of the Green Cross Corp, named as such since 1971, and whose main business is pharmaceuticals.

In Japan a flag with a green cross (midori-juji ) on a white field is frequently flown on construction sites and factories to encourage workers to remember health and safety. It also appears on badges and arm bands for the same purpose and is occasionally seen as a cross-within-a-cross.

The poster on the right, for example, was seen at Oimachi's railway station in Tokyo, to announce the government's health / safety / sanitation measures.

Ironically, a green cross was used to identify the contents of a deadly artillery gas shell during World War I. These were fired by the British and German armies in Europe and released suffocating gasses. 

Also ironically for this colour symbolising 'environmental friendliness', green happens to be one of the most toxic colours there is for dyeing fabrics, paper, plastics, and many other materials used for packing 'green' products. According to the German chemist Michael Braungart's design book Cradle to Cradle, it's impossible to dye such products without contaminating them. Composting or recycling such products contaminates other material. Green is not very environmentally friendly.

The most common green shade used in plastic is Pigment Green 7; it is organic but contains chlorine and is linked to cancer and birth defects. Pigment Green 36 contains chlorine and bromide, and Pigment Green 50 contains cobalt, titanium nickel and zinc oxide. Older pigments used by artists contained arsenic. Indeed, such poison is believed to have caused the death of Napoleon.

Is this nature's way of saying to mankind that trying to replicate nature, even the colours of nature, can lead to doom?

Maybe. But don't let any of this stop you from reaching for the First Aid Box (with its green cross) when you need to.

All colours are used by all religions but certain colours have special significance. For example, in Abrahamic religions:

Red in CrossChristianity means 'blood'. Liturgically, green is used on Palm Sunday and Pentecost.
Green in Allah in ArabicIslam means 'life'. It was the Prophet's favourite colour (along with white and black). The word "green" stems from the Proto-Indo European root ghre-, "grow".
Blue in Star of DavidJudaism means 'divinity'. Shavuot is celebrated with greenery to symbolize the early summer and early harvest season.

The lush green flora of Ireland inspired United Irishman, Dr William Drennan to coin the sobriquet Emerald Isle in his 1795 poem "When Erin first rose".

A similar white cross on a green background is the trade mark for the multinational pharmaceutical Green Cross Corporation

The green First Aid symbol differs from the St. Lazarus Cross St. Lazarus Cross in that the arms of the Green Cross are shortened, forming a humetty cross.

midori-juji means 'green 10 symbol', since the Japanese character for 10 is

Gases, such as chloropircin, diphosgene, carbonyl chloride and chlorine, which irritate the soft mucous membranes of the respiratory tract and can lead to death. See also white cross gas, yellow cross gas and blue cross gas.

A pharmacy shop is more commonly called "chemist's" in the UK, "drugstore" in the US, and rarely called what it really is; a "medicine shop".

...and not a "body repair shop" which would confuse owners of bent vehicles.
