No place for clothes
When your clothes get heavy with paint, strip.
That's what many in the crowd did, stripping down to their bikinis and trunks after organisers emptied litres of paint into the crowd.
Said 18-year-old Rachelle Hernandez: "After a while, I just had to take it off. My shirt looked like a painting.
"I was covered in paint. I even found green paint in my ear after the party."
Besides being shot with water guns, revellers also got their paint on at "splash zones" and body art painting booths around the beach.
Other fringe activities included a graffiti wall where local graffiti artists left their mark, and a photo booth lit with ultra-violet light for that extra glow.
