Color blindness significantly impacts web accessibility primarily by affecting how users perceive and differentiate colors. Those who are color blind struggle to distinguish between certain shades, which can lead to confusion when color is used as the sole means of conveying important information. For example, if a website utilizes color-coded alerts (like red for errors and green for success) without any accompanying text labels or symbols, users who are color blind may not recognize these indicators and can miss critical information or messages.

This issue emphasizes the importance of designing web content that is accessible to all users, including those with visual impairments related to color perception. To ensure clear communication, designers and developers should incorporate multiple cues, such as text descriptions, icons, or patterns, along with color to convey information effectively. This strategy supports a more inclusive design, allowing users with color blindness to navigate websites and interact with digital content without barriers.
