A influência das cores na acessibilidade e usabilidade de interfaces: comparação entre esquemas fixos e personalizáveis

Abstract

This study investigates the influence of color on the accessibility and usability of digital interfaces, with emphasis on the comparison between fixed and customizable color schemes. The research is based on the premise that visual design can act either as a barrier or as a facilitator for individuals with visual impairments, such as color blindness and low vision. Using an exploratory and quantitative approach, a questionnaire was administered to users diagnosed with visual disabilities, using the institutional portal of the Federal Institute of Piauí– Campus Picos as the reference interface. The study aims to understand how different chromatic approaches affect navigation experience and content perception, considering aspects such as autonomy, visual comfort, and adaptability. The data analysis contributes to the proposal of accessibility guidelines based on WCAG 2.2, focusing on the development of more inclusive and flexible interfaces.
