The oranges should not be viewed as a means for defining what you can bring to the table, but rather a mere categorization. However this categorization is essential to helping others find you and allows them to quickly see where your interests lie, which in turn helps to build a stronger professional and social network all the more quickly.

the vision orange should appeal to those who want to be involved in the writing or directing of productions.

the talent orange is for those who are typically on camera. This is the orange for everyone from actors to extras to lion tamers.

the shoot orange is for all who are involved in how images are captured. Whether you hold the camera, tell someone how to hold the camera, or set up lights, this is the orange for you.

the sound orange is for anyone who is involved in what viewers can hear. Boom operators, mixers, composers this is the orange for you.

While all of these oranges could arguably be art, in this context the orange is for those involved in all visual elements seen on set or in post.

the post orange is for all those who bring it together at the end. Editors to compositors, visual effects directors to look developers.

the produce orange is for those who are involved in high level decisions and organization.
