Cardiff City supporters hope a meeting called for by the club's owner Vincent Tan for Thursday will lead to them playing in blue again.
Tan has been at the heart of Cardiff's controversial rebrand from blue to red.
Attendances have dropped since Premier League relegation last season and Tan has invited a cross section of supporters to a "consultative meeting".
"I think there's going to be something on offer," said David Craig, vice chair of the Cardiff City Supporters Trust.
"Otherwise why call the meeting unless there is an intention to get something constructive out of it?
"The obvious issue is the one of rebranding," added Craig, who has been invited to the meeting.
Craig told BBC Wales Sport he was unaware of any agenda for the meeting, but said the Trust had sent the club a letter with suggestions for possible items of discussion.
The most popular one put forward by the group's members, he said, was the desire to see the club return to its traditional blue home shirt and badge.

"I think it's an extremely important meeting potentially because it's the club whose called it at the request of Vincent Tan. I've been told this is a window of opportunity. There are no promises on the table of a return to blue or anything like that, but these matters will be discussed. The club have been very diligent in inviting fans of all strands of opinion about the way forward for Cardiff City. I do think this could turn out to be a very decisive meeting indeed."
Tan has not attended any Cardiff City games this season and is not expected to be at today's meeting, but asked club chairman Mehmet Dalman and CEO Ken Choo "to invite a cross-section of supporters and stakeholders" for the gathering.
The club's average home attendance in the Premier League in 2013-14 was 27,430, but that has fallen to 19,333 since relegation to the Championship.
A crowd of just 4,194 which saw the Bluebirds beat Colchester 3-1 in the FA Cup third round was the lowest ever Cardiff City attendance at Cardiff City Stadium, which opened in 2009.
Cardiff fan Ben James, who runs the Twitter page 'View From The Ninian' fan podcast, hopes the meeting proves fruitful.
"There's got to be something behind this that is going to lead to something," he said, "or that they [Cardiff City] give the fans what they want, because otherwise it's just a publicity sham."
Cardiff City have asked all fans and stakeholders to send their views via email ahead of the meeting.
"Emails will be verified against the supporter and stake holder data base," said a Cardiff City spokesman.
"We treat all views with equal significance to those received in the meeting tonight and these emails will be passed on."
