Redundant Cues

While the difference between red and green is blaring to most of us, it is imperative in good design to think about users who aren’t like us– say, users with color vision deficiencies. This is where redundant cues come in, a specific method for adding accessibility to a product.

Examples of redundant cues include the old Apple chat interface (as shown in class) [2]:
