Which three colors should not be contacted in an electric/hybrid electric vehicle?

In electric and hybrid electric vehicles, certain colors are designated to indicate high-voltage components that should not be contacted to ensure safety. Specifically, the colors blue, orange, and yellow are commonly used to represent high-voltage electrical systems.

Blue typically denotes components related to the electrical system, indicating areas where caution is required. Orange is universally recognized for high-voltage systems, signaling that specific components can carry a dangerous electric charge. Yellow might also indicate various critical components requiring caution, depending on the manufacturer's standards.

Understanding these color codes is essential for safely working around electric and hybrid vehicles, as improper contact with these colored components can lead to serious electric shocks or other hazards.
