The effectiveness of digital learning environments depends largely on the usability and accessibility of their visual components. Contrast levels in graphical interfaces play a key role in ensuring visibility, engagement, and a positive learning experience. However, not all educational details are equally noticeable to all users. A lower contrast, if strategically applied and visually striking, can still draw attention and enhance the perception of critical information. This technique is often used in video games, where selective emphasis on certain elements directs the player’s focus and improves information processing. This study examines whether high contrast alone guarantees visibility and user-friendliness in digital learning environments. Specifically, we analyze the extent to which WCAG guidelines align with educational needs and whether alternative contrast configurations can maintain readability while reducing visual fatigue. By applying these insights, educators and developers of computational science training materials can refine digital tools, enhance user engagement and improving knowledge retention among learners.
