In 1606, people didn't have pantone guidelines to keep colours consistent - nor did it matter. Heraldry only has a limited number of colors. Variations on blue exist but are not standard, so any blue could be used.
It just so happened that the English were already using a blue, in the Blue Ensign being used by English ships. Wikipedia even suggests its ...
Silver means white.
The art and science of classic European flag design is called "Heraldry". Classic heraldry refers to color as "Tincture". Tinctures are separated into 5 colors:
and 2 metals:
In classic medieval sculpting artworks depicting heraldry (like ...
It might be a Confederate flag, specifically the Van Dorn battle flag:
Quoting its wikipedia description:
The Van Dorn battle flag is a historical Confederate flag with a red field depicting a white crescent moon in the canton and thirteen white stars; and trimmed with gold cord. In February, 1862, Confederate general Earl Van Dorn ordered that all units ...
Technically, it's not a flag it's a surcoat. It represents the coats of arms of her family. In heraldic terms, the display of these arms are known as impalement. In this case, the arms on the dexter side (her right) represent the arms of her husband, Edward II (the coat of arms of England) and on the sinister side (her left) those of her family (the coat of ...
It is Tannu Tuva. When Mongolia broke out from China in 1911, this little territory was separated from China (which was in a state of internal turmoil during the first years of the Republic of China) but was not claimed by Mongolia.
In practice, Tannu Tuva was a Soviet satellite country, only the Soviet Union and Mongolia recognized it.
Stalin annexed it ...
The pattern you show is called a Nordic Cross. Searching for flags with Nordic crosses comes up with the Flag of Vendsyssel, which is a traditional district of Denmark and of Jutland. (See Vendsyssel at wikipedia)
The proposed flag of Vendsyssel in Denmark was introduced by the mayor
of Hjørring in 1976, and is used to some extent.
The flag is ...
The Roman conquest of Britain was undertaken in 43 CE by four legions:
Legio II Augusta
Legio IX Hispana
Legio XIV Gemina
Legio XX Valeria Victrix
These same legions still comprised the garrison a dozen years later during the uprising by Boudicea
Legio II Augusta remains in Britain until at least the 3rd century.
Legio IX Hispana is sent to ...
Wikipedia (in German) has a long and fascinating article on the history of the German national colours. Without getting in all the details, it seems that the link with the colours of the Holy Roman Empire symbols isn't historically established and might have been a later rationalisation for the choice.
Still according to this article, the first use of these ...
Actually, no Roman legions appear to have been based in London.
There was a fort in the north-west of the Roman city, built early in the second century, which could have held a garrison of about 1000 soldiers. However, this was the guard available to the governor of the province, rather than any particular legion.
In fact, five legions are known to have ...
According to Wikipedia, this is the naval flag of the Netherlands' Secretary of Defense.
This flag would be flown on a ship that the Dutch Secretary of Defense is using as a headquarters (also referred to as a flagship). This type of flag is known as a rank flag.
In Europe and especially in France the events of the Paris Commune and the use of the red flag there set for good the red flag as the symbol of the socialist revolution and not "just" the revolution.
The Icelandic flag never had any actual silver colour in it and was never meant to contain any silver.
In the quote argent is meant to convey just white. It is used in an outdated and imprecise form of traditional descriptive language.
While it's true that:
The word for white in Latin is "albus", not argentum. Argentum means silver.
In heraldry ...
There are isolated instances of flag desecration in America's colonial and revolutionary past, but the perpetrators were not especially influential.
Although a scattering of flag desecration incidents speckled American
history prior to the twentieth century, none of them aroused any form
of institutionalized legal response until shortly before 1900. ...
The book A História dos Símbolos Nacionais, published by the Brazilian Senate, states that indeed,
[The flag] was conceived by Jean-Baptiste Debret, French painter and
founder of our Academy of Fine Arts, inspired by some military flags
used in his country at the time of the Great Revolution and the
Napoleonic Era, from which he copied the ...
That's Biel / Bienne, see its coat of arms:

Swiss historian Markus Kutter confirms it in Zwischen Jura, Vogesen und Schwarzwald, 32. Hinter die Fassade verbannt (in German):
Auf der ursprünglichen Fassade waren nur 11 Wappen abgebildet, also die achte alten Orte, ergänzt durch Freiburg und Solothurn, dazu ...
The colors come from the heraldic tradition, especially European and former European colonies' flags and coats of arms. In this summary on heraldry the basic heraldic colors are:
If you check existing flags, you will find that they are almost all made in these colors. According to the link provided ...
The association with saints is probably correct. Red and blue were indeed respectively the colours of Saint Denis and Saint Martin.
The early history of the French flag is lost in obscurity, and it is not always easy to trace the various modifications that it has undergone. At the earliest date of which we have record we find the kings of the Franks ...
The flag is known as the Black Standard of Muhammad. There are many variants of the flag, and as far as I can tell the variant used by ISIS is original, but other variants have been used by many groups before.
The flag can either be a pure black flag, or it may have the Shahada ("There is no god but Allah. Muhammad is the messenger of Allah.") printed on it ...
I would say it is the flag of Deventer. It's a city towards the east of the Netherlands, that prospered by trading with the various cities around the North and Baltic Sea coast as well as Scandinavia.
It is situated at the river IJssel, which feeds in the Zuiderzee (back then, before Afsluitdijk changed it). The port of Amsterdam (depicted on the painting) ...
There is evidence to suggest that many were manufactured, but were not actually purchased for normal use. As described in an article on the use of American flags in popular fashion:
The modern debate over the ‘correct’ use of the flag in clothing
started in the 1960s. One incident concerning flags and clothing
occurred be- cause of the admission of ...
(There's a pretty complete description of the association between the red flag and revolution on Wikipedia's page on the color red)
It can be associated with revolution (at least as far back as the French revolution, before that in Europe it was sometimes associated with monarchy) and communists see themselves as revolutionaries.
Red is associated with ...
Because those other pennants already had internationally recognized meanings, that would have resulted in dangerous ambiguities:
Note also the very specific instruction:
The Council ruled that "no ceremony shall be accorded this flag which shall not be dipped in salute to warships or merchant ships of any nationality".
There was very intentionally no ...
Some preliminary breadcrumbs:
There appears to be some mystery around how English Wikipedia can be so certain about the unreferenced assertion. It seems rather certain that the five-pointed star was introduced in several forms onto flags before, but only made into standardised law in 1936. Before that, the information available seems too confusing as to how ...
Not as precise answer as I'd like, but it might lead you to the correct answer with further research. Googling for "hungarian heraldry crescent 13th century" yields at least one crescent, from the Sas coat of arms, which indeed has a crescent in it.
Sas or Szász (origin: Slavic for "Saxon", Polish: Sas, Hungarian: Szász, Romanian: Saş) ...
As was pointed out by others, colours in national flags are derived from older coat of arms or other symbols derived from medieval heraldry. That one itself become more or less formalized in the early 13th century, from a habit taken (especially during the Crusades) to hoist highly distinguishable colour patterns so as to promote warrior recognition on a ...
My guess is that they were meant to be service flags. These were usually rectangular flags with a wide red rectangular border and a white middle area. In the middle area, a person would place a number of stars indicating the number of loved ones you had serving (blue star for serving, gold for killed).
For a public (non family) display of such a flag, like ...
I don't think it's an eagle. It looks more like a Gryphon. In that case, it could be from a number of Baltic states or areas, especially Pomerania.
But I'm pretty sure it's actually a lion, or more specifically, the Flemish Lion, indicating that the ships are from Flanders, which is the Dutch-speaking part of Belgium nowadays, or from the Netherlands in ...
The flag design most closely associated with Napoleon would be his personal command flag. If he had one.
Pending the discovery of the design of any personal flag of Napoleon, the flag design most associated with him would be the regimental colors carried on the same staffs as the eagles of his regiments.
The Swiss and Piedmontese coats of arms and flags might both possibly, repeat possibly, have originated as symbols of loyalty to the Holy Roman Empire.
Flags and coats of arms of Switzerland and Piedmont are certainly visually related.
The question of whether they are historically related is complex and has no certain answer.
