It belongs to the blue color family and has very low saturation and brightness, making it appear almost black in certain lighting conditions.

Due to its dark nature, it's essential to consider contrast and accessibility when using Gulf Blue in design to ensure readability and usability.

The hex color #010D57, also known as Gulf Blue, presents significant accessibility challenges, particularly for text-based content. Its extremely low luminance value creates insufficient contrast against both white and light-colored backgrounds. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text to ensure readability for users with visual impairments. Gulf Blue typically fails to meet these ratios, making it difficult for many individuals to distinguish text from the background. To improve accessibility, it's essential to pair Gulf Blue with very light or white text, and even then, careful testing is needed to confirm sufficient contrast. Using this color for important visual elements like buttons or links should be avoided unless accompanied by clear, high-contrast indicators. Designers should always prioritize accessibility and perform contrast checks using online tools to ensure content is usable by everyone.
