The hex color #0C37A8, a deep, vibrant blue reminiscent of International Klein Blue, presents some accessibility challenges, particularly regarding color contrast. When used as a background, it's crucial to pair it with light-colored text (white or very light shades of yellow or green) to ensure sufficient contrast for readability, adhering to WCAG guidelines for color contrast ratios. For smaller text or intricate graphics, the contrast becomes even more critical. Avoid pairing it with dark or similarly toned colors as this will result in a low contrast ratio, making it difficult for users with visual impairments to perceive the content. Consider providing alternative color schemes for users who might benefit from them, offering higher contrast options. When using this color for interactive elements, such as buttons or links, provide clear visual cues beyond color alone to indicate the element's interactive state. This could include adding an underline, a border, or a change in shape or size upon hover or focus.
