In the RGB color model, it is composed of 1.18% red, 6.67% green, and 38.82% blue. This composition gives it a strong blue bias, making it appear rich and intense. Colors similar to Gulf Blue often convey a sense of trust, authority, and intelligence, making it a popular choice in various fields, including branding, design, and even fashion. However, its darkness presents accessibility concerns and careful usage is recommended.

The hex color #031163, also known as Gulf Blue, presents significant accessibility challenges. Its extremely low luminance results in very poor contrast against both white and light-colored backgrounds. This makes text and other user interface elements nearly unreadable for individuals with visual impairments, including those with low vision or color blindness. Adhering to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Gulf Blue fails to meet these standards in almost any context with default settings. To improve accessibility, it should be paired with very light shades, and even then, thorough testing with accessibility tools is crucial to ensure readability. Using this color sparingly, if at all, is highly advised in interfaces that prioritize usability.
