I have always asked myself what is the most frequent combination of colours; what is the most used colour on flags, and I decided to research frequency and quantity of colours on flags of independent countries.

The results are sorted in different categories:

Frequency of particular colour on researched flags Area of particular colour on researched flags Number of one, two three...-coloured flags Frequency of particular colour combinations on researched flags Firstly, I had to differentiate colours. I have divided them in 10 groups:

W -white

N - black

R - red

B - blue

V - green

Y - yellow/gold (I have merged those colours, because sometimes is hard to determine yellow from gold on certain flags)

O - orange

M - brown (maroon)

G - gray

P - purple

There are 192 flags of independent countries in the world. The most frequent are the three-coloured flags. no of colours no of flags % 1 1 0.52 2 43 22.40 3 76 39.58 4 45 23.44 5 14 7.29 6 7 3.65 7 4 2.08 8 2 1.04

And the most frequent combination of colours is White/Red/Blue...

The number of flags containing particular colours are:

Colour No. % Red 148 77.08 White 140 72.92 Blue 102 53.13 Yellow/Gold 89 46.30 Green 87 45.31 Black 59 30.73 Orange 9 4.69 Brown 9 4.69 Gray 6 3.13 Purple 2 1.04

The second colour, as you can see is not the same by area and by frequency (blue & white) ....... And the champions of whiteness are (results in % of flag area):

Black:

Red:

Blue:

Green:

Yellow/Gold:

Spain - 0.10 Nicaragua - 0.04

(only two flags contain purple)

There are 30 plain tribands (with equal stripes/bands) out of the countries of the world.

6 of them are "2-coloured tribands":

24 are "3-coloured tribands":

% of colour area of all tribands:

R - 25.81 W - 21.50 B - 19.36 V - 15.05 Y - 10.75 N - 4.30 O - 3.23
