Quote from: Color
Once your chocobo has reached a mature stage of development, it is possible to match it with other chocobos. The resulting offspring may exhibit the attributes or coloring of its parents.

There should have color already

Quote from: SE
It was stated in the June 19 Topics that a chocobo’s appearance would change along with its attributes. Due to an extension of the testing period, these changes will now be implemented in a following version update.

Beginning Chocobo Raising
The process of chocobo raising begins when you trade an egg obtained from a shop or battlefield to a VCS chocobo trainer (located in the stables of the three starting nations). You won’t be able to tell the attributes or coloring of your chocobo until the egg hatches.
*Note that you cannot trade another egg to a chocobo trainer once the chocobo raising process has begun. Also, the process of raising a chocobo must be continued in the nation where the egg was traded.

Chocobos will eventually be retired from the raising process. It is possible to voluntarily retire an adult chocobo by speaking with the VCS trainer and selecting the option “Retire your chocobo.”
A retired chocobo will be registered on a VCS registration card, and taken into the care of the VCS.
*A retired chocobo can no longer be involved in the chocobo raising process.
*A chocobo with which you have chosen the option “Give up chocobo raising” will not be registered on a VCS registration card.
*A VCS registration card will only be issued once. Please take care not to throw the card away.

- Matchmaking and Riding Retired Chocobos
Trade the VCS registration card to the VCS trainer. You will then have the option to obtain a chococard or register to call your chocobo.
