In the RGB color model, it has the values (0, 5, 85). This particular shade leans heavily towards the blue end of the spectrum, making it appear almost black.

The hex color #000555, also known as Gulf Blue, presents significant accessibility challenges, especially when used as a background color for text. Its very low luminance of approximately 0.002 makes it difficult to achieve sufficient contrast with lighter text colors, potentially violating WCAG (Web Content Accessibility Guidelines) requirements. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended to ensure readability for users with visual impairments. Using #000555 for text on a white background, or vice versa, would result in a very low contrast ratio, failing accessibility standards. To improve accessibility, consider using lighter shades of blue or pairing #000555 with much lighter colors like whites or very pale yellows. Thoroughly test color combinations with accessibility tools to ensure compliance.
