The hex color #1C3957, also known as Cello, presents certain accessibility considerations, especially in web design. Its relatively low lightness value indicates it's a darker color, which means careful attention must be paid to color contrast. When used as a background, it necessitates light-colored text to ensure readability for users, including those with visual impairments. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text, as per WCAG guidelines. Tools like contrast checkers can accurately assess the contrast ratio. If the color is used for interactive elements, such as buttons or links, hover and focus states should also maintain sufficient contrast to provide clear visual cues for users navigating with keyboards or assistive technologies. Proper semantic HTML and ARIA attributes are crucial to enhance accessibility further.
