The color #0247B1, also known as Cobalt, presents some accessibility challenges, especially regarding color contrast. When used as a background color, it necessitates very light text (white or near-white) to ensure sufficient contrast for readability, ideally aiming for a contrast ratio of at least 4.5:1 as per WCAG guidelines. Conversely, as a text color, it requires a very light background. Combining Cobalt with darker colors can make text illegible for users with visual impairments. Designers should use color contrast analysis tools to verify compliance with accessibility standards. Additionally, providing alternative visual cues, such as icons or text labels, alongside color coding can significantly improve accessibility for all users, including those with color vision deficiencies.
