At the end of the first quarter of 2016, there were 6,841,315 cars in silver or aluminum.
This is 22.5% of the total 30,459,456 licensed cars in the UK, though a fall from the 25% of silver cars on the road in 2013.
However, silver was still able to fight off competition from its closest rivals to keep its position at the top of the chart.
According to the data, which comes from analysis of DVLA figures by RAC Cars, black is the next most popular colour among drivers.
There are now 5,915,527 black cars in the UK, with the colour holding its position at second place from last year.
Blue completes the top three most popular car colours, though the data suggests it has fallen out of favour.
The proportion of blue cars in use has dropped from 21% in 2013 to 18.6% today, accounting for 5,689,516 licensed vehicles this year.
It comes as figures from the Society of Motor Manufacturers and Traders revealed that more than 109,000 cars rolled of production lines in the UK last month, making it the sector’s best August for 14 years.
There was a big drop between the popularity of blue cars and the colour’s nearest competitor.
Fourth place was taken by grey cars, of which there are 3,710,965, or just 12.2% of the total.
Red came in at the fifth spot on the chart, claiming 3,237,326 cars, up 4% on the 2013 total of 3,104,114.
The data also reveals a huge upsurge in the popularity of white cars, suggesting it could be a contender for one of the top spots in future.
Although currently occupying sixth place in the table, its percentage share of cars has grown dramatically from just 5% in 2013 to 9% in 2016.
This is a 91% increase on the 1,348,950 white cars in 2013, taking the total in 2016 to 2,833,084.
Green just managed to edge up over the one million mark to come in at seventh place.
There are now 1,066,496 green cars on the road – or 3.5% of the total.
The top 10 list was completed by beige, yellow and brown, which each has under 1% of all cars.
RAC Cars spokesman Pete Williams said that drivers’ choice of colour can be influenced by a number of factors.
“Some people can be very particular or superstitious about the colour of their cars, always having to have the same colour whereas others are clearly influenced more by fashion,” he said.
“White is very much the colour of the moment which is why it’s rising up the rankings, but it has a long way to go before it becomes as popular as silver, black and blue. It will be very interesting to see how long this trend in new cars lasts.”
