Throughout the last 1000 years red has become a consistent motif for military clothing and heraldic imagery in England. What are the reasons for this? Are there economic, environmental (eg. dyes used in wool trade), social or political reasons for the primacy of this colour?
Although I can't answer for heraldry, there were a number of factors that influenced the red colour of English, then British military uniforms.
During the 16th to early 20th centuries, primary colours and red especially helped to blur soldiers together, so that the enemy from a distance found it difficult to distinguish numbers and individuals accurately. Remember that back then, long-range weapons were highly inaccurate, so blending in with the crowd afforded you an element of safety.
However, up close and personal during the battle, things were fairly chaotic with lots of smoke, etc., so having your kinsmen stand out from your enemy and being able to quickly recognize friend from foe was also a boon.
But still, why red? That actually came down to a number of factors as well.
During the civil war, red dye was the most abundant and easily available dye to use. Red is also a simpler dying process, requiring only a single stage as opposed to other colours, and is cheaper.
Culturally red evolved to become a national colour for whatever reasons, and so we ended up sticking with the colour.

There have been a number of great answers, but I would add one other reason.
The Patron Saint of England is St George, whose colours are a red cross on a white background (still the flag of England today).
What better colours to wear into battle than those of your patron saint who fought a dragon and won!?
Red dye was cheap at the time the decision was made. No seriously they had decided they needed a uniform colour for the army and Red was just cheaper at the time.
see en.wikipedia.org/wiki/Red_coat_(British_army) "The adoption and continuing use of red by most British/English soldiers after the Restoration (1660) was the result of circumstances rather than policy, including the relative cheapness of red dyes"
Actuallly it goes back to the English Civil War, and Cromwell's raising of the 'New Model Army'- This was the first british army to be given a formal uniform, one piece of which was a leather jerkin- which was tanned in a rusty, orangy-red colour- prior to this english regiments were uniformed in whatever colour the Lord who raised them decided. The only exception to this was the Yeoman Guards of the Tower- A military unit raised by Henry VIII, uniformed in the colours of the royal standard (Red & Gold) and the oldest continuous military unit in the world.
After the restoration of Charles II, the regiments that were in the 'New Model Army' retained their red-ish tunics, and the rest of the army followed suit, albeit with facings of different colours based on regional tradition e.g. Lincolnshire regiments had Lincoln Green, the West Kents had Buff (Thus accounting for their regimental nickname 'The Buffs'). The use of scarlet was only brought in during the late 18th century, when dye technology meant that true red was possible (and was cheaper than trying to reproduce the more traditional russet colour).
Red was only for line infantry regiments, and certain cavaltry regiments. The artillery, engineers and lancers wore Dark Blue, and light Infantry regiments wore Dark green & Some Hussar units wore black. Farriers of all regiments wore Buff coats with red facings.
Red is considered a Royal color (that and blue are the main colors) they can be found in almost every coat-of-arms. Red wasn't adapted until fabrics were used during the crusades (12th century).
Red and blue appeared on the same standards and robes because they compliment each other. When the french decided to use Blue as their main color the British naturally swayed to the red because blue troops fighting blue troops would make the battle field hectic and chaotic.
This is why the American Continental Army chose blue to be their color, the opposite of the british red.
Why Red though?
- Red would blend in with the fire of muskets and other guns
- Red would blend into the brick forts and structures the british were famed for
- Red is an aggressive color, studies have shown that if you played against yourself in a game of soccer the one in red would win.
Red is the color of fire and blood, so it is associated with energy, war, danger, strength, power, determination as well as passion, desire, and love.
Red is a very emotionally intense color. It enhances human metabolism, increases respiration rate, and raises blood pressure. It has very high visibility, which is why stop signs, stoplights, and fire equipment are usually painted red. In heraldry, red is used to indicate courage. It is a color found in many national flags.
Red brings text and images to the foreground. Use it as an accent color to stimulate people to make quick decisions; it is a perfect color for 'Buy Now' or 'Click Here' buttons on Internet banners and websites. In advertising, red is often used to evoke erotic feelings (red lips, red nails, red-light districts, 'Lady in Red', etc). Red is widely used to indicate danger (high voltage signs, traffic lights). This color is also commonly associated with energy, so you can use it when promoting energy drinks, games, cars, items related to sports and high physical activity.
Light red represents joy, sexuality, passion, sensitivity, and love. Pink signifies romance, love, and friendship. It denotes feminine qualities and passiveness. Dark red is associated with vigor, willpower, rage, anger, leadership, courage, longing, malice, and wrath. Brown suggests stability and denotes masculine qualities. Reddish-brown is associated with harvest and fall.
In an age of smoky battlefields and inaccurate muskets it is often more important for your own leaders to be able to find the right units than to 'hide' from the enemy. Thus the bright colored uniforms. You needed mass fire to keep cavalry away and beat down the other side's units and you needed to stand to reload. So infantry wasn't behind any cover.
Even in those days, units that did hide in combat - skirmishers and light infantry - did have more concealing uniforms.
After that, you need to just make sure your brightly colored uniforms are colored different than your opponents. Red suited the English so they chose it.
