Don't remember my source but found this, it's about how basic 7 scent categories can invoke varying moods
Researchers have identified seven basic scent categories that can invoke varying moods. The first category is floriental scents. These offer romantic, dream-based moods that are often idealistic in nature. They create emotional places where feelings can serve as a master, not just a guide.
Another category is aldehyic-floral scents. These tend to project a classical, elegant, or cultured mood. They can evoke feelings of wealth, power, and freedom.
Oriental scents are the third category. These offer introspection, sensitivity, and reflection as their base moods. These can evoke a deep, spiritual understanding and intense relationship bonds.
An additional category is fruity-floral scents. These project a carefree, playful, and cheerful mood. These fragrances create curiosity and an openness to change that would not ordinarily exist without them.
Another category is powdery-aldehydic scents. These scents offer an independent, unconventional, and unfettered mood. These scents offer an artistic freedom.
The sixth category is fresh green floral scents. These project a dynamic, active, and extroverted mood. These scents invoke feelings of risk and the exhilaration that goes with that risk.
The final scent category is chypre scents. These fragrances project professional, pragmatic, and self-assured moods. These are no nonsense scents that offer a feeling of practicality.
