Grand Blue's 0.688 brightness ties it for second in the dataset — a figure that makes
perfect sense for a show set in the blinding Aegean light of a scuba diving club at a
coastal university. The overexposed whites of sky and water dominate the palette. It is
one of the few anime where the environment itself functions as the primary character: the
Mediterranean light is not just setting, it is atmosphere, invitation, and joke delivery
system. The brightness arc is essentially flat because the sun never sets on episode one.
