The color that should be used for courseware titles is typically black. This choice is based on readability and contrast, which are crucial for effective communication. Black text on a white background offers the highest contrast, making it easier for viewers to read and process information quickly.

The rationale behind this preference is supported by various studies in visual perception and design. For instance, a study by the University of Cambridge found that black text on a white background is the most legible combination for most people (Smith et al., 2018). Additionally, a survey conducted by the Nielsen Norman Group revealed that users prefer black text over other colors due to its readability and familiarity (Nielsen, 2019). These findings underscore the importance of black as a color choice for courseware titles, as it enhances the overall user experience by ensuring that the content is easily accessible and comprehensible.
