What is the color of artificial intelligence? [on hold]

What is the color of artificial intelligence, or the color which represents AI in the eyes of general public?

What is the reason for that? Is there any sociological research on this or related topics?

I'm designing the product which will have AI agent, probably in the form of character. This character will suggest changes to user content (tasks, work items). Changes like: move the task to next stage, link related entities. I'm considering to distinguish this suggestions/changes with color to indicate that this change was made by IA agent but not fellow human. Just to give people a heads-up.

The best insight I have at this point is from 99% Invisible podcast Future screens are mostly blue episode, which is based on Make It So book. I wonder if there anything else any should know.
