This calculator is used to calculate what chocobo feed you will need to get from your current colour to your desired colour. It simply calculates the difference in RGB colours, then works out on the fruits that are needed to attain each value using an increment of +/-5.
You must feed in all of the recommended fruits in one single feed and cycle it through the different fruits as you feed. You will see a message that your chocobo is now beginning to grow new feathers every single time the colour changes as you feed.
Now, this confirms that your chocobo will be a different colour in about 6 hours.
The colours that are available for your Chocobo are mostly the same ones that you can dye your in-game clothing in. Some exceptions will be there of course that include the dye tab with the ‘general-purpose’ colour names.
This is the section with the ‘Pure White’, the ‘Jet Black’, the metallic colours or pastels, amongst others. Sadly, no shiny metal Chocobos are allowed.
