The hex color #1f3a64, also known as Cello, presents specific accessibility considerations for web development. Its relatively low luminance can pose challenges in ensuring sufficient contrast against lighter background colors. According to WCAG guidelines, text and interactive elements should have a contrast ratio of at least 4.5:1 against their background. When using #1f3a64 for text, it's crucial to pair it with a very light color to meet these standards, enhancing readability for users with visual impairments. For larger text (14pt bold/18pt regular and up), a contrast ratio of 3:1 is acceptable. Careful evaluation with contrast checkers is highly recommended to validate compliance. Additionally, avoid using #1f3a64 as the sole indicator for interactive elements; provide supplementary cues like underlines or icons to accommodate users who may have difficulty distinguishing colors.
