A contrast ratio of at least 4.5:1 is recommended for body text and 3:1 for larger text elements to comply with WCAG guidelines. Insufficient contrast can hinder users with visual impairments, including those with low vision or color blindness, from effectively perceiving the content.

Tools for checking color contrast ratios can be valuable in this process, helping designers and developers create inclusive designs that cater to a broad range of users.
