The color #2C4BBA, also known as Cerulean Blue, presents moderate accessibility challenges. Its contrast ratio against white is approximately 3.9:1, which meets the WCAG AA standard for normal text but falls short of the AAA standard. For larger text (14pt bold or 18pt regular), it passes the AA standard. When used as a background color, pairing it with light text such as white or very light grays is crucial to ensure readability. Additionally, avoid using this color for essential interactive elements like buttons or links without sufficient contrast, as users with visual impairments may struggle to identify them. Consider providing alternative visual cues, such as underlines or icons, to enhance usability. Thorough testing with accessibility tools is highly recommended to validate the color's suitability across different user needs and devices. Ensuring that all content remains accessible and usable is a paramount focus.
