Identifying colours in the absorption spectrum with an app

This study addresses the challenges faced by students with colour blindness during the exploration of light spectra, emphasizing the crucial adaptation of educational materials for effective learning. The proposed solution, characterized by its low-cost and straightforward implementation, involves the use of smartphone apps, notably the ‘ColorADD,’ to assist students who cannot perceive colours in understanding spectral phenomena. This topic is integrated into the curricula of both high school and undergraduate physics courses in Portugal and Brazil. This approach represents a tangible opportunity to promote inclusive scientific education, fostering active participation and ensuring equal opportunities for colour-blind students without compromising their overall visual perception.
