General Information about Gulf Blue (#000B57)

In the RGB color model, it is composed of 0 red, 11 green, and 87 blue. In the CMYK color model, which is commonly used for printing, it consists of 100% cyan, 87% magenta, 0% yellow, and 66% black. This color is often associated with trust, loyalty, and intelligence, similar to other shades of blue.

It can also be seen in branding that wants to give off a trustworthy vibe.
The hex color #000B57, also known as Gulf Blue, presents considerable accessibility challenges, particularly in web design. Its extremely low luminance value of 0.005 makes it unsuitable for text or interactive elements against a white or light background. 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 this color's darkness, achieving sufficient contrast requires using very light colors like white or pale yellow. However, careful consideration is needed as some light colors can create a jarring effect. It is recommended to use contrast checkers to verify compliance and explore alternative color combinations to ensure inclusivity and readability for users with visual impairments. Designers should also be mindful of users with cognitive disabilities, for whom high contrast can sometimes be overwhelming.
