General Information about Gulf Blue

The hex color #000C57, also known as Gulf Blue, is a deep, dark shade of blue. It belongs to the blue color family and is often associated with sophistication, depth, and calmness. In the RGB color model, it consists of 0 red, 12 green, and 87 blue. In the CMYK color model, used for printing, it is composed of 100% cyan, 86% magenta, 0% yellow, and 69% black. This color is often used to convey trust, stability, and authority, making it a popular choice for corporate branding and professional websites. Its low luminance also means that it is not ideal for applications where high visibility is required, such as warning signs or call-to-action buttons without adjustments for accessibility.

The hex color #000c57, also known as Gulf Blue, presents significant accessibility challenges, especially in text-based applications. Its low luminance value of 0.008 makes it difficult to provide sufficient contrast against lighter backgrounds, failing WCAG's AA and AAA compliance for normal text sizes. To ensure readability, it is essential to use significantly lighter colors for foreground elements, such as text or icons, with a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular). Furthermore, consider avoiding using this color for critical interactive elements without proper contrast, as users with visual impairments may struggle to perceive them. Using color contrast checking tools during development can help verify compliance and improve the overall user experience. Employing techniques like text shadows or borders can mitigate contrast issues to some extent but may not be sufficient for full accessibility.
