The blue ocean turns green when the light illuminates the wave. The salt spray is being blown back by the off shore winds.
"Carefully determine what pleases the Lord. Take no part in the worthless deeds of evil and darkness; instead, expose them. It is shameful even to talk about the things that ungodly people do in secret. But their evil intentions will be exposed when the light shines on them, for the light makes everything visible. This is why it is said,
Awake, O sleeper, rise up from the dead, and Christ will give you light." Ephesians 5: 10-14 NLT
