A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is crucial. Insufficient contrast can severely hinder users with visual impairments, including those with low vision or color blindness.

Additionally, avoid relying solely on color to convey information; use text labels or icons to ensure inclusivity for all users.
