Culture code is a key method developed by Clotaire Rapaille to understanding the type of culture, unique cultural features encoded in some form of information to identify the culture.
Cultural code defines a set of images that are associated with a particular set of stereotypes in our minds. This is sort of cultural unconscious, which is hidden even from our own understanding, but is also seen in our actions. The cultural codes of a nation helps to understand the behavioral responses characteristic of that nation's citizens. The key codes in understanding specific behaviors differentiate between religion, gender, relationships, money, food, health, and cultures.
There are three kinds of global cultural codes: preliterate (traditional), literary and screen full. Each type contains basic cultural code, opened to self-generation of new, secondary cultural codes.
The concept of "cultural code" is considered in the book of Clotaire Rapaille The Culture Code: An Ingenious Way to Understand Why People Around the World Live and Buy as They Do.
