There are three colors available for Agro. They are treated as items that are a reward for defeating colossi. All require completing the following Time Attacks:
- White - defeat 10 colossi (Normal difficulty level),
- Brown - defeat 14 colossi (Hard),
- Black with ICO ornate - defeat 16 colossi (Hard).
The chosen color does not affect the statistics of the horse. More info can be found in chapter "Rewards for Time Attacks".
