Which fluid is indicated by the color "red" for power steering?

The color red is typically associated with automatic transmission fluid (ATF) in many vehicles, and this holds true for power steering fluid as well in some models. Automatic transmission fluid is commonly dyed red for easy identification and helps in differentiating it from other fluids in the engine compartment.

While hydraulic fluid may also be used in some power steering systems, it is often not colored red. Instead, hydraulic fluids can come in various colors depending on the manufacturer and formulation. Similarly, engine oil is usually amber or dark brown, and brake fluid can appear clear or yellowish, but not red. Therefore, the identification of power steering fluid as red points explicitly to the use of automatic transmission fluid in this context, confirming that it is the correct answer.
