The color #1B3C61, also known as Cello, presents some accessibility challenges, particularly concerning color contrast. When used as a background color, sufficient contrast with text is essential for readability. White or very light shades of yellow or green will generally provide adequate contrast. It's crucial to evaluate the contrast ratio against WCAG (Web Content Accessibility Guidelines) standards to ensure compliance. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Tools like WebAIM's Contrast Checker can be invaluable in this assessment. Avoid pairing #1B3C61 with similarly dark colors, as this will render text and interface elements illegible for users, especially those with visual impairments. Thoughtful consideration of color combinations can improve the user experience significantly.
