The hex color #303F6B, also known as Rhino, presents certain accessibility considerations, particularly in web design. Its relatively dark hue impacts its contrast ratio against lighter backgrounds. To ensure readability and usability, it's crucial to pair this color with sufficiently light text or interface elements. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to meet WCAG (Web Content Accessibility Guidelines) standards. Using online contrast checkers can help determine appropriate color pairings. When #303F6B serves as a background, lighter shades of yellow, white, or pale pastels usually offer adequate contrast.

Also, when using this color, consider providing alternative cues besides color alone, such as text labels or icons, to convey meaning, ensuring accessibility for color-blind users.
