The hex color #18385D, also known as Cello, presents some accessibility challenges, particularly when used as a background color for text. Due to its low luminance, it requires careful consideration of the foreground color to ensure sufficient contrast. 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. A light color such as white or a bright yellow would be a suitable choice for text to meet these contrast requirements. When using this color for interactive elements like buttons or links, it's crucial to provide clear visual cues to indicate their active or hover states. For example, changing the background color slightly or adding a border can improve usability for users with visual impairments. Furthermore, consider providing alternative styling options for users who prefer high-contrast modes.
