The hex color #1E3557, also known as Cello, presents some accessibility challenges, particularly concerning color contrast. When used as a foreground color for text, it requires careful consideration of the background color to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. This dark shade of blue necessitates a very light background to meet these standards. Using lighter shades of yellow, white, or very light grays can help achieve adequate contrast. It's crucial to test color combinations with accessibility tools to confirm compliance and ensure that users with visual impairments can easily perceive the content. Avoid pairing #1E3557 with other dark colors, as this will almost certainly result in insufficient contrast. Providing alternative styling options, such as high-contrast themes, can also enhance accessibility for a wider range of users.
