Race-winning British Touring Car Championship team Ciceley Motorsport will run with a new livery in its 2017 campaign.
Adam Morgan's Mercedes-Benz A-Class will run a red and black colour scheme in deference to backers Mac Tools, which has stepped up to take headline sponsorship of the car.
It marks a significant change for the Morgan-run Mercedes, which has run in yellow and black since it made its debut in 2014 with backing from Wix Filters.
Morgan, a four-time race winner in the BTCC, said: "We have worked really closely with the guys at Mac Tools over the last three years and are delighted to have them as our new title sponsor.
"It's incredible to have the company as title sponsor now having built a great relationship with them and a three-year deal illustrates the commitment the company has to the teams and the championship.
"I can't wait to stand on the top step of the podium in my Mac Tools overalls for the first time and repay the company's faith in us."
Ciceley also operate a team in the Renault UK Clio Cup and has so far signed three drivers for the 2017 season.
