Final answer:
Your knowledge of hair color is stored in the subconscious level of consciousness, which houses information that we can access when needed but do not continually think about actively.
Step-by-step explanation:
Your knowledge of your hair color resides in your subconscious level of consciousness. This is the level where information and knowledge that we are not actively thinking about are stored, but which we can bring into our conscious awareness with ease when required. The subconscious is a powerful aspect of our minds housing not only simple known facts about ourselves, such as hair color, but also deeply ingrained skills and learned behaviors that we can perform without conscious thought.
For example, the act of daydreaming while driving demonstrates how certain actions can be carried out competently from our subconscious without active conscious awareness. This principle is rooted in our biological rhythms and the sophisticated integration of sensory input and motor activity orchestrated by the cerebral cortex. The subconscious mind influences our behavior, and oftentimes we perform complex actions under its guidance without the necessity of deliberate intent or awareness.
