The hex color #03145B, also known as Gulf Blue, presents some accessibility challenges, primarily due to its low luminance. When used as a background color, it requires very light text (white or near-white) to ensure sufficient contrast for readability. 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 to meet AA compliance. Given the darkness of Gulf Blue, careful consideration must be given to font sizes and weights. Additionally, it's important to avoid using this color for essential graphical elements or controls without providing high-contrast alternatives, especially for users with visual impairments. Testing with accessibility tools is highly recommended to validate the color's usability for a wide range of users.
