Cardiff are considering a proposal to change the colour of their kit to red.
Press Association Sport understands it is one of a number of options being considered by the club's board as part of a rebranding exercise to boost their chances of attracting greater revenues.
Cardiff - whose nickname is the Bluebirds - lost their npower Championship play-off semi-final tie against West Ham to leave them facing another season in England's second tier.
The club have been keen to stress that any changes "will recognise the legitimate interests of the fans" and that there will be further consultation with them following a board meeting to discuss a series of proposals next week.
Cardiff have also reached an agreement with the Cardiff Blues rugby team for the latter to terminate their lease at the Cardiff City Stadium with effect from June 1 and move to the Arms Park.
