Abstract: An integrated light and fragrance system automatically controls (150) aromatic effects (125) based on a user's control (111) of lighting effects (115). The system accepts one or more sets of lighting-fragrance correlations (165) from which to determine a preferred aromatic effect (161, 162) from a selected lighting effect (151, 152). Optionally, these sets of lighting-fragrance correlations (165) are provided by third-party vendors (310) who employ the skills of expert ambiance designers. In an alternative embodiment, the system may also use these sets of lighting-fragrance correlations (165) to control lighting effects (115) based on a user's control (121) of the fragrance effects (125). In each of these embodiments, the user merely controls (111, 121) a desired first effect (115, 125), and a suitable second effect (125, 115) is created to enhance the first effect (115, 125).
