RGB Color Model

CMYK Color Model

I've joint the competition to study something...
This is my latest "product" which is saved in two kind of color mode, RGB and CMYK.

This composition is the combination of lines, texture and movement.
Several layers can be seen through each other. In the same “mass”, for instance, we can see various levels of opacity in the same yellow curvy wave.
There is pattern of check.
The three main colors, red, yellow and blue are used with different saturations. Red and yellow elements represent for boats and the sun. Blue is for the pure ocean.
“Hot” colors red and yellow go with the “cool” one, blue keep the balance “temperature” of the whole picture.
