Matching clothing and accessories: Color-blind individuals may have difficulty coordinating and matching clothing and accessories, leading to potentially mismatched outfits.

Identifying ripeness of fruits and vegetables: Color-blind individuals may struggle to determine the ripeness of fruits and vegetables based on color, which can affect their ability to make informed choices while grocery shopping.

Understanding color-coded information: Color-blind individuals may have difficulty interpreting color-coded information, such as charts, graphs, and maps, which can hinder their ability to understand and communicate data effectively.
