The Cardiff City Supporter Trust and the Supporters club have acknowledged the need to grow their international reputation but believe the proposed changes to both the colour of the Cardiff strip and the Bluebirds badge are a step to far.
To highlight their anger over the proposals the Supporter Trust Board have called an emergency meeting this Saturday.
The Supporter Trust Board said:
"A football club is not like any ordinary business which can be rebranded and traded without any thought for the fans.
"Cardiff City Football Club belongs to supporters and their families who have supported it through thick and thin. Most want to stick with the blue colours and the Bluebird on the crest. Of course we would like the City to become an international brand, but at what price?
" While we welcome the continued investment by our Malaysian owners, these changes ignore the history of the club and the attachment that generations of fans have for the logo and blue strip.
The club announces a revised kit and logo, along with 'ambitious' plans for a new training facility, as part of a 'major' investment.
Cardiff City say that talks between Dato Chan Tian Ghee and the club's board have ended.
The owners of Cardiff City meet to discuss the future of the club on Tuesday.
