According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal-sized text and 3:1 for large text (14pt bold or 18pt regular) against its background. Therefore, pairing #1A5181 with light backgrounds like whites (#FFFFFF) or light yellows (#FFFFE0) is crucial to meet accessibility standards. Tools like contrast checkers can assist in verifying sufficient contrast. It's also essential to avoid using this color for critical information if the user's color perception is impaired. Providing alternative cues such as icons or text labels alongside color coding enhances accessibility for all users.
