The hex color #100c51, also known as Gulf Blue, presents some accessibility challenges, particularly concerning color contrast. When using this color for text or interactive elements, it is crucial to ensure sufficient contrast against the background. According to WCAG (Web Content Accessibility Guidelines), the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. Given the darkness of Gulf Blue, it is best paired with very light colors like white or pale yellow to meet accessibility standards. Tools like contrast checkers can help verify compliance. When Gulf Blue is used for decorative elements, it’s impact on accessibility is significantly reduced. The primary concern revolves around text readability and the usability of interactive components.
