We have developed an analytical method to investigate the stellar populations in a galaxy using the broad‐band colours. The method enables us to determine the relative contribution, spatial distribution and age for different stellar populations and gives a hint about the dust distribution in a galaxy. We apply this method to the irregular galaxy NGC 3077, using CCD images in U, B, V and R filters.
