My product to I use is Primary and Secondary colors to represent the ocean!

 

 

Primary Ocean

 

The first picture on my background I used primary colors is made out of dark shades from under the sea, the flowers are blooming bright as they can trying to find the path so I used the primary colors to light the way.

 

   Secondary Ocean

 

   The second picture uses secondary colors to show the darkness on the outside, while the background is light like the ocean on a bright sunny day.  It's like a burning fire flames making the darkness pure evil, so they have to find the way to seal that much evil forever so it won't come out.
