Members of Cardiff City Supporters' Trust have voted against plans by the club's owners to change the colour of the club's shirts and badge.
Nine out of ten members said they felt they had not been consulted sufficiently over the changes.
"The club now needs to reflect very carefully on the views of some of its most loyal supporters." said Tim Hartley, the chair of the trust.
"We believe that as a minimum, all season ticket holders should have been consulted in advance.
"The results again highlight the need for elected supporter representation on the board of Cardiff City Football Club", he added.
Trust members voted 54-7% to 43.8% against the changes, with 1.9% abstaining.
Cardiff City Supporters' Trust has responded to this morning's announcement.
Trust chairman Tim Hartley said the group "welcomes" the proposed investment and plans to tackle the club's debts.
He warned that there needed to be more clarity over the actual commercial benefits over the changing of the club's home shirt to red.
Mr Hartley also called for supporters to have representation on the board of the club. "It is vital that the voice of the ordinary supporter is heard", he said.

There are still questions that need to be answered such as what happens to the proposed investment if there is no deal over historical debts with Langston and how much will actually be invested and over what period.
So, the red revolution has returned to Cardiff City.
This morning the club revealed that plans to change the strip to red and swap the bluebird badge for a dragon were back on the table.
As part of the package, money will be invested to pay off the Cardiff's debts - including £15 million owed to the Langston Corporation - develop new training facilities, and strengthen the squad.
Speaking about the rebranding, Chief Executive Alan Whitely said it was "not a decision that has been taken lightly or without a great deal of thought or debate."
He went on to say that the board would "do their utmost to uphold, protect and promote the values and virtues which the club stands for."
The deal is seen as one which will bring long-awaited financial stability to the Championship club. But it's sure to create a renewed stir with fans who fear the club's heritage is being hijacked.
Makes no sense whatsoever.....throwing away decades of hard work growing a fan base in Cardiff who eat sleep and eat BLUE!...

We have nothing but the best interests of the club and its supporters to heart and will look to conclude matters as soon as possible to the best possible outcome. I would also like to personally thank the many who have sent in messages of heartfelt support and appreciation, either directly or via the club.
Last night the plans to re-brand Cardiff City football club were dropped after an uprising by fans who feared a break with history and tradition.
The offer of £100m of investment has now been dropped by the investors fuelling speculation about the future of the club.
