The hex color #121155, also known as Gulf Blue, presents significant accessibility challenges, especially for text-based content. Its low luminance value of approximately 2% means it offers very little contrast against black backgrounds and similarly dark colors. Consequently, using #121155 as text on a white background or vice versa would fail WCAG (Web Content Accessibility Guidelines) AA and AAA standards for color contrast. To ensure accessibility, designers should avoid using #121155 for text or interactive elements without employing a significantly lighter background color. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Utilizing color contrast checkers can assist in determining if a chosen color combination meets accessibility standards. Darker shades can be used as background.
