Nowadays, home football strips show incremental change year-on-year: a new trim on the shorts and a sponsor change here, an Angry Birds logo on a shirtsleeve there.
But year-on-year evolution has begotten revolution, and many of the current Premier League sides would look very different if they were to line up in their original colours. Courtesy of the brilliant HistoricalKits.co.uk, here are the original colours of the current sides in England's top-flight.
Arsenal
If you wander far enough back in time - to a time that Arsene Wenger wasn't even in charge - Royal Arsenal wore colours that have since been adopted by Manchester United.
AFC Bournemouth
Bournemouth were initially founded as Boscombe, and wore colours closer associated with Stoke City nowadays.
Brighton and Hove Albion
Initially founded as Brighton United, the club wore colours later made famous on English touchlines by Brian Clough.
Burnley
It was 1910 until Burnley decked themselves out in Claret and Blue. Before that, they dressed as jockeys.
Chelsea
The Blues have been faithful to, er, blue for every year of their history...bar the first.
Crystal Palace
Nope, that's not West Ham. It's Palace.
Everton
Initially known as St Domingo's, we first saw the blue and white that would define the club generations later:
The club we now know as Everton, however, had this incredible black number with South American-style sash when the club was renamed. Bring it back!
Leicester City
Initially known as Leicester Fosse, the future Premier League champions had an Everton-esque sash:
When they dropped the 'Fosse', however, they proved to be an inverse of Everton.
Liverpool
The Reds were not always, er, red.
Manchester City
The club we now know as City was named in 1894, and while there has been revolution at the club of late, there has ben very little in terms of kits:
Manchester United
In 1879, there arrived a club known as Newton Heath LYR....
...who soon became Newton Heath. They waited a couple of years to adopt the green-and-gold colours, and instead wore this at the beginning:
Then, in 1902, they became known as Manchester United.
Newcastle United
Formerly East End FC, Newcastle United came into being in 1892, and they waited two years before donning black and white. In the intervening years, they were yet another side to wear red.
Southampton
The club were initially founded as St Mary's YMA, and they devised one of the finest kit designs of all time.
When they became known as Southampton, however, things took a turn for the mundane.
Stoke City
Stoke became Stoke FC which then, in 1925, became Stoke City. The name - and colours - has survived.
Swansea City
Swansea began their existence as Swansea Town, and wore white.
Spurs
Spurs' first home kit is now used as their away strip.
Watford
Watford began life in 1898 as a circus tribute act.
West Brom
West Brom began life in 1881 looking like half a Battenberg cake.
West Ham
Now claret and blue, the Hammers were initially loyal to blue only.
