Abstract
The colors are widely used in website projects. Besides their aesthetic purpose, they are meant to influence the user, highlighting information and guiding navigation. Depending on how they are used, their correct identification and interpretation are determinant factors in the user’s experience. Considering that approximately 10% of the world’s population have some color vision deficiency, those people may find various hurdles using the internet. This research investigates the use of Windows 10’s color filter to circumvent accessibility issues for color blind users. Color blind participants evaluated a few scenarios using an online form to interpret elements distinguishable by color. Each scenario represented a situation found on websites and contained two images, an original one and another modified by the color filter. Results showed an improvement in most scenarios but in different ways for different types of color blindness. The benefit was the most evident on the protan type color blind group, especially in situations where the service offered by the website depends on user action, like online checkouts, filling forms or browsing through links. The scenario that stood out the most was online checkouts, giving room for deeper research on the subject. The group with deutan color blindness, on the other hand, showed the least expressive results but rated the experience the highest. The study raised points of attention for future research: situations where the filter hindered the participant’s experience and the cases where they did not perceive any difference.
