The Malaysian backers of the Welsh club are proposing switching kit colours from blue to red and replacing the bluebird with a dragon
According to the Cardiff City Supporters Trust, the owners' plans to further their investment in the club comes with a condition of changing the kit colours from blue to red and implenting a dragon in the club crest, in place of the trademark bluebird.
"We were shown a design of the logo, Cardiff City will be playing in red, they will be wearing a dragon on their chests," trust chairman Tim Hartley told BBC Wales.
Vice-chair Tracey Marsh added: "I feel like they've got us over a barrel and we are not going to take this lying down."
Malaysian businessman Tan Sri Vincent Tan Chee Yioun who is estimated to be worth £800m is said to be the man behind the club, while fellow Malaysian Datuk Chan Tien Ghee serves as Chairman.
The planned investment by the owners includes the building of a new training ground and increasing the capacity of the existing stadium.
Cardiff City have responded to the comments on their official website.
"We would like to assure supporters that any decisions will include the long term interests of our supporters, our community and the survival and development of Cardiff City Football Club in a highly competitive and modern sporting industry," read the statement on www.cardiffcityfc.co.uk.
"As a club we also appreciate the importance of our history, along with our position within the community."
Cardiff City reached their first ever League Cup final earlier this year where they were beaten by Liverpool on penalties. They finished sixth in the recently concluded Championship season and saw their bid for promotion to the Premier League scuppered after losing 5-0 on aggregrate to West Ham United in the play-off semi-finals.
