Abstract: The colour brightness calculation of the RGB colour system used in electronic devices is an important research topic. According to the human eye's perception of light, this paper proposes a new colour brightness calculation model, trying to find the coefficient of the variables through data collected from experiments. This model provides an intuitive colour brightness processing method for web-based course designers or interface designers. It enables the designers to easily get a precise brightness value of a colour. Also, the proper selection and use of colours based on this model has the potential to make web-based courses and other computer programmes more appealing to users.
