The hex color #010B5C, also known as Gulf Blue, presents significant accessibility challenges due to its very dark hue. When used as a background color, it requires extremely light text to achieve sufficient contrast for readability, ideally a pure white (#FFFFFF). According to WCAG guidelines, a contrast ratio of at least 4.5:1 is necessary for normal text and 3:1 for large text. Given its low luminance, #010B5C will likely fail these requirements with most text colors except the very lightest. Therefore, it is essential to use a contrast checker to ensure compliance. Furthermore, consider users with visual impairments who may struggle to differentiate between shades of dark blue. Providing alternative visual cues and ensuring that interactive elements have sufficient focus indicators are crucial for inclusive design. Avoid using this color for essential information without adequate contrast.
