Yellow over green bicolour with red vertical stripe at hoist 
containing a black five-pointed star.
Željko Heimer, 23 Oct 2001
The symbolism of this flag is inherited from the symbolism of 
Ghana, from which it comes: an arrangement 
of the pan-African colours with the 
black star of Africa added. 
Its proportions are, as in the party 
flag, 1:2.

The Album 2000 [pay00] says  ≅1:2.
The construction details are given, but since the overall ratio is 
approximate, the construction details are inevitably so. The two 
horizontal stripes are of the same size, of course, and the width of 
the vertical stripe is one third of the total length.
The star appears to be inscribed in a circle with the center in the 
midpoint of the red stripe and of diameter equal to two units used on 
the scheme (i.e. 1/3 of hoist).

I read somewhere in the 1st constitution of Guinea Bissau (or maybe in 
the Statutes of P.A.I.G.C.) that the three 
areas of the flag are to have the same area, saying nothing about the 
final ratio of the flag — therefore a, say, 
2:3 ratio might be not really a mistaken 
depiction.

The protocol manual for the London 2012 Olympics 
[loc12], with info approved by 
each NOC, gives for Guinea-Bissau PMS 032 red,
109 yellow, 355 green and black.
Ian Sumner, 11 October 2012
I should say that some of these colors seem to me to be just too dark: 
PMS 032, for one, is British red, which is known to 
be darker than regular red, while PMS 109 is suitable for the national 
flag of Germany, knowingly “darker” than 
regular yellow. The green stripe of the national flag of Guinea-Bissau is 
noticeably brighter than the the green areas of the national flags of 
Brazil and Portugal (these 
three flags are easy to find flown along in coherent displays), which are 
known to be prescribed as dark green — so, PMS 355 seems okay.

The Presidency website has a page about national symbols with illustrations:
https://www.presidencia.gw/sobre-a-guin%C3%A9-bissau-1 
I haven’t found 
any governmental document about exact shade of colors.

Other sources for colors:
There is no official source that gives exact 
colors of the national flag; these are all approximate colors from these 
documented sources.
The Flag Manual - Beijing 2008 gives Pantone colors: 
PMS 032 (red), PMS 355 (green), PMS 102 (yellow), and PMS Black.
The 
Album des Pavillons 2000 [pay00] gives 
approximate color in Pantone and CMYK systems:
Red: Pantone 186c, CMYK 
0-90-80-5
Yellow: Pantone 116c, CMYK 0-15-95-0
Green: Pantone 355c, CMYK 
100-0-90-0
The Album des Pavillons 2023 already specifies the color of 
the flags in three color systems.
Red: Pantone 186c, CMYK 14-100-79-4, RGB 
200-16-46
Yellow: Pantone 116c, CMYK 0-21-93-0, RGB 255-204-0
Green: 
Pantone 355c, CMYK 84-12-100-1, RGB 0-149-48
Vexilla Mundi gives colors in 
Pantone system: PMS 116C (yellow), PMS 355C (green), PMS 186C (red), and PMS 
Black.
Wikipedia gives color values as 
follows:
Black: Pantone Black c, CMYK 0-0-0-1, RGB 
0-0-0, Hex #000000
Red: Pantone 032c, CMYK 0-0.92-0.82-0.19, RGB

The Independence of Guinea Bissau was proclaimed by the National Assembly, 
which was basically appointed by the Partido Africano para a Independência da 
Guiné e Cabo-Verde (PAIGC), the independence party which not only fought for 
independence from Portugal for Guinea Bissau from Portugal, but also for Cape 
Verde (Cabo Verde).
The same day [23 September 1973] as the proclamation 
of independence, the National Assembly proclaimed the (first) Constitution of 
the Republic of Guinea Bissau. It was published in the very first edition of the 
Boletim official República da Guiné-Bissau, (Government Gazette), of 4 January 
1975. Chapter 1, Article 2 describes the flag and other symbols as follows:
Constituição da República da Guiné-Bissau
Capítulo 1 Dos fundamentos o 
objectivos 
Artigo 2º: A Bandeira Nacional da Guiné-Bissau é constituída por 
três bandas com a mesma superfície, sendo uma vermelha disposta verticalmente e 
marcada com uma estrela negra. As outras duas são dispostas horizontalmente, 
sendo a superior amarela e a inferior verde.
O Hino Nacional da Guiné-Bissau 
é Esta é a Nossa Patria Amada.
A divisa da Guiné-Bissau é Unidade, Luta, 
Progresso.
Translated:
Constitution of the Republic of Guinea-Bissau
Chapter 1 
From fundamentals to objectives
Article 2: The Guinea-Bissau National Flag 
shall consist of three stripes bands with the same surface, one being red 
arranged vertically and marked with a black star. The other two are arranged 
horizontally, the upper one being yellow and the lower one being green.
The 
National Anthem of Guinea-Bissau is This is Our Beloved Country.
Guinea-Bissau's currency is Unity, Struggle, Progress.
The second 
constitution of the Republic of Guinea Bissau dates from 16 May 1984. Chapter 1, 
Article 22 describes the national symbols as follows:
Constituição da 
República da Guiné-Bissau
Título I Princípios fundamentais Da natureza e 
fundamentos do Estado Artigo 22º:
1. Os símbolos nacionais da República da 
Guiné-Bissau são a Bandeira, as Armas e o Hino.
2. A Bandeira Nacional da 
República da Guiné-Bissau é formada por três faixas rectangulares, de cor 
vermelha, em posição vertical, e amarela e verde, em posição horizontal, 
respectivamente do lado superior e do lado inferior direitos. A faixa vermelha é 
marcada com uma estrela negra de cinco pontas.
3. As Armas da República da 
Guiné-Bissau consistem em duas palmas dispostas em círculo, unidas pela base, 
onde assenta uma concha amarela, e ligadas por uma fita em que se inscreve o 
lema «UNIDADE LUTA PROGRESSO». Na parte central superior insere-se uma estrela 
negra de cinco pontas.
Translated:
Constitution of the Republic of Guinea-Bissau
Title I 
Fundamental principles Of the nature and fundamentals of the State Article 22:
1. The national symbols of the Republic of Guinea-Bissau are the Flag, the Arms 
and the Anthem.
2. The National Flag of the Republic of Guinea-Bissau is 
formed by three rectangular bands, red, in a vertical position, and yellow and 
green, in a horizontal position, respectively on the upper and lower right 
sides. The red band is marked with a black five-pointed star.
3. The Arms of 
the Republic of Guinea-Bissau consist of two palms arranged in a circle, joined 
by the base, on which a yellow shell rests, and connected by a ribbon inscribed 
with the motto “UNIT LUTA PROGRESSO”. A black five-pointed star is inserted in 
the upper central part.
As far as I am aware there is no further 
legislation into the national symbols. Only the Penal Law from 13 October, 1993 
protects them against wrong use. It was published in : Boletim oficial, 
Suplemento, nº 41, 13 October, 1993. It reads:
Decreto-Lei nº 4/93, de 13 de 
Outubro. Código Penal
Título VII - Dos crimes contra a seguranca do Estado
Artigo 224º: (Ultraje de símbolos nacionais)
Quem, publicamente, por palavras, 
gestos ou divulgações de escrito, ou por outro meio de comunicação com público, 
ultrajar a República, a bandeira ou hino nacional, as armas ou emblemas da 
soberania guineense ou faltar ao respeito que lhe é devido, é punido com prisão 
até três anos.

Article 224: (Outrage of national symbols)
Anyone who, publicly, by words, gestures or written disclosures, or by other 
means of communication with the public, outrages the Republic, the national flag 
or anthem, the weapons or emblems of Guinean sovereignty or fails to respect due 
to him, is punished up to three years in prison.

Historical photo of late 1974 or 
1975 showing the flag hanging from a wire/rope: Like a normally 
hoisted flag, it can bee seen from both sides — with the 
top to the viewer’s right hand (as the 
photo shows), on one side, and with 
the top to the viewer’s left hand, on the 
other

I suspect that there’s not really a fixed prescription and the 
only care is to have all flags (identical or not) turned to the same 
direction — this is especially relevant when said vertical hoisting 
(hanging) is done from a stretched rope or wire, not against/on a wall, 
and can thusly be seen from both sides (and this is, in my opinion, the 
proper, vexillologically informed way to deal with vertical hoisting at 
all).

The protocol manual for the London 2012 Olympics

flag that is simply the horizontal version turned 90 
degrees clockwise.

In the book História da Guiné e Ilhas de Cabo Verde, 
by PAIGC, 1974, the 
image on the cover is a vertical 
Guinean-Bissau flag (with a “leaner” 
star). The book does have only one image on the cover page, which is 
like the national flag in vertical position, with the difference that it 
has an irregular star, pointed to the top (of the image/book).

A photo on the book História da Guiné e Ilhas de Cabo 
Verde, by PAIGC, 1974, shows the 
assembly of Madina do Boé (place of the unilateral declaration of 
independence, 24 Sep. 1973) in the bush or jungle with lots of small 
flags and a large one 
in vertical position in a rope like clothes to dry. The main flag, and 
some small, are shown with the darker (the green) stripe to the right, 
which means we see the reverse side of the flag (it’s not a 
reversed image, because there are some bands with words that we can 
read). The photo is captioned «Bruna Amico © Gamma, Paris». 
With the examples of this book and Cabral’s poster, I wonder if 
there is trend or old habit to use the Bissau-Guinea flag in vertical 
position.

The main element is a black star, that is part of traditional Pan-African 
symbolism, and is often referred to as the Black star of Africa. A seashell at 
the bottom unites two symmetrical olive branches. The seashell is symbolism for 
the location of the country on the west coast of Africa. The red scroll contains 
the national motto of Guinea-Bissau: "Unidade, Luta, Progresso".
