Cardiff have confirmed the Bluebirds will now play in red after the club's Malaysian owners formally unveiled a new image for the Welsh side.
The switch - which also includes a new club crest and takes effect immediately - comes after the club's hierarchy approved the decision at a board meeting.
The club have unveiled three new strips - a red home shirt, a blue away strip, and a third kit, which is mainly black.
All new kits bear a redesigned badge, incorporating a main image of a dragon, with a small bluebird inserted underneath, and carrying the slogan "Fire and Passion".
In addition to the new kit, the club have announced plans to build a brand-new training ground, pay off the historical Langston debt, provide manager Malky Mackay with a substantial transfer kitty, and explore the possibility of expanding the Cardiff City Stadium.
A statement on Cardiff's official website, cardiffcityfc.co.uk, said: "Following a comprehensive review of wider supporter feedback via email, letters, media coverage and polls run via the official Supporters Club and Media Wales and as a consequence of the above commitment, Cardiff City Football Club will also reactivate rebranding proposals.
"With a view to exploiting and maximising its brand and commercial revenues in international markets, which it is hoped in turn will bring success to the club locally, whilst also attracting new partners and investors."
