The color commonly associated with protons in atomic models is red. This convention helps in distinguishing between different subatomic particles; red is typically used to represent protons, while other colors are assigned to neutrons and electrons. The use of distinct colors for different particles simplifies the visualization of atomic models, making it easier for students and scientists to understand and communicate about atomic structure. In many educational resources and illustrations, red effectively conveys the positive charge of protons, thus reinforcing the idea that they contribute to the overall positive charge of the nucleus of an atom.
