This document discusses different types of intuition. It defines "grey intuition" as thoughts that arise from one's experiences and knowledge but seem to come from an unknown origin. In contrast, "blue intuition" comes from an unknown source without a clear origin. Most intuition experienced is grey intuition from stored experiences. True blue intuition is rare. While blue intuition may be inspiring, grey intuition based on one's knowledge and experiences is more practical and likely to benefit one's life, family, and career. An ideal is to use both blue and grey intuition together whenever possible.
