Bhutan
divided diagonally from the lower hoist-side corner; the
upper triangle is yellow and the lower triangle is orange; centered
along the dividing line is a large black and white dragon facing
away from the hoist side; the dragon, called the Druk (Thunder
Dragon), is the emblem of the nation; its white color stands for
purity and the jewels in its claws symbolize wealth; the background
colors represent spiritual and secular powers within Bhutan: the
orange is associated with Bhuddism, while the yellow denotes the
ruling dynasty
Bolivia
three equal horizontal bands of red (top), yellow, and green
with the coat of arms centered on the yellow band; red stands for
bravery and the blood of national heroes, yellow for the nation's
mineral resources, and green for the fertility of the land
note: similar to the flag of Ghana, which has a large black
five-pointed star centered in the yellow band; in 2009, a
presidential decree made it mandatory for a so-called wiphala - a
square, multi-colored flag representing the country's indigenous
peoples - to be used alongside the traditional flag
Bosnia and Herzegovina
a wide medium blue vertical band on the fly
side with a yellow isosceles triangle abutting the band and the top
of the flag; the remainder of the flag is medium blue with seven
full five-pointed white stars and two half stars top and bottom
along the hypotenuse of the triangle; the triangle approximates the
shape of the country and its three points stand for the constituent
peoples - Bosniaks, Croats, and Serbs; the stars represent Europe
and are meant to be continuous (thus the half stars at top and
bottom); the colors (white, blue, and yellow) are often associated
with neutrality and peace, and traditionally are linked with Bosnia
Botswana
light blue with a horizontal white-edged black stripe in
the center; the blue symbolizes water in the form of rain, while the
black and white bands represent racial harmony

Brazil
green with a large yellow diamond in the center bearing a
blue celestial globe with 27 white five-pointed stars; the globe has
a white equatorial band with the motto ORDEM E PROGRESSO (Order and
Progress); the current flag was inspired by the banner of the former
Empire of Brazil (1822-1889); on the imperial flag, the green
represented the House of Braganza of Pedro I, the first Emperor of
Brazil, while the yellow stood for the Habsburg Family of his wife;
on the modern flag the green represents the forests of the country
and the yellow rhombus its mineral wealth; the blue circle and
stars, which replaced the coat of arms of the original flag, depict
the sky over Rio de Janeiro on the morning of 15 November 1889 - the
day the Republic of Brazil was declared; the number of stars has
changed with the creation of new states and has risen from an
original 21 to the current 27 (one for each state and the Federal
District)
British Indian Ocean Territory white with six blue wavy horizontal stripes; the flag of the UK is in the upper hoist-side quadrant; the striped section bears a palm tree and yellow crown (the symbols of the territory) centered on the outer half of the flag; the wavy stripes represent the Indian Ocean; although not officially described, the six blue stripes may stand for the six main atolls of the archipelago
British Virgin Islands
blue, with the flag of the UK in the upper
hoist-side quadrant and the Virgin Islander coat of arms centered in
the outer half of the flag; the coat of arms depicts a woman flanked
on either side by a vertical column of six oil lamps above a scroll
bearing the Latin word VIGILATE (Be Watchful); the islands were
named by COLUMBUS in 1493 in honor of Saint Ursula and her 11 virgin
followers (some sources say 11,000) who reputedly were martyred by
the Huns in the 4th or 5th century; the figure on the banner holding
a lamp represents the saint, the other lamps symbolize her followers
Brunei
yellow with two diagonal bands of white (top, almost double
width) and black starting from the upper hoist side; the national
emblem in red is superimposed at the center; yellow is the color of
royalty and symbolizes the sultanate; the white and black bands
denote Brunei's chief ministers; the emblem includes five main
components: a swallow-tailed flag, the royal umbrella representing
the monarchy, the wings of four feathers symbolizing justice,
tranquility, prosperity, and peace, the two upraised hands
signifying the government's pledge to preserve and promote the
welfare of the people, and the crescent moon denoting Islam, the
state religion; the state motto "Always render service with God's
guidance" appears in yellow Arabic script on the crescent; a ribbon
below the crescent reads "Brunei, the Abode of Peace"
Bulgaria
three equal horizontal bands of white (top), green, and
red; the pan-Slavic white-blue-red colors were modified by

stripe, has been removed
