You dye a chocobo because you want to be seen riding a spiffy colored chocobo. Therefore, the chocobo which you want to dye should be the chocobo registered to your chocobo whistle.
Make sure you register the chocobo (preferably retired) you want to your chocobo whistle via the chocobo trainer of your home nation (Hantileon@Sandy, Zopago@Bastok, Pulonono@Windy). Then take the chocobo dye to the VCS Chocobuck Exchange Vendor located outside the entrance to your home nation's Chocobo Race Center (Palabelle@Sandy, Gavoroi@Bastok, Robino-Mobino@Windy).
