What is the difference between black-and-white Dream points and color Dream points?

Black-and-white Dream points are the Dream points that have been credited to your account, but cannot be redeemed for bookings yet. To turn your black-and-white Dream points into color ones, your balance should be at least 1,500 Dream points. As soon as you reach this balance, all Dream points that have been credited to your account become color points. This also applies to all new Dream points that you will receive in the future.

Colorful Dream points are the dream points that can be used for payment.
