Gulf Blue evokes a sense of depth and sophistication, making it a versatile choice for various design applications.

The hex color #010B5D, also known as Gulf Blue, presents several accessibility considerations for web developers. Its very dark hue results in a low contrast ratio against standard white backgrounds, which can pose significant challenges for users with visual impairments. According to WCAG guidelines, sufficient contrast is crucial for readability and usability. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. This color likely fails to meet these ratios against light backgrounds, necessitating careful selection of foreground text colors. Using lighter shades of yellow, orange, or green can provide better contrast and improve accessibility. Additionally, developers should use tools to verify contrast ratios and consider providing alternative color schemes to accommodate users with different visual needs or preferences. Ensuring proper color contrast is essential for creating inclusive and user-friendly web experiences.
