Insufficient contrast can make content difficult or impossible to read for users with visual impairments, including those with low vision or color blindness. A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text or graphical elements. Careful consideration of color pairings is essential to ensure readability and usability.
