Since 2005 the Desert Fireball Network (DFN) has been collecting data on meteors that have appeared throughout the Australian sky. This study aims to further understand and improve the classification of meteors and meteorites using fireball data taken by cameras in the DFN. Currently, little work has been carried out into the classification of meteors based primarily on their colours. The DFN offers one of the largest catalogs of meteor photometric colour, magnitudes and trajectory information in the world, which makes the DFN an unparalleled resource. This study has allowed the curation of information from multiple sources and further analysis to be undertaken. From preliminary results it appears that the Southern Taurid meteor shower may be both more red and less green in visual appearance, when compared to other showers. Overall, this has proved to be an interesting new avenue for the classification of meteor showers, and we plan to investigate further through our access to more data from the wider DFN collaboration.
