This color is not widely used in print media due to its relative darkness, but it can be found in digital designs and is mostly appreciated when used as an accent.

The hex color #051358, often referred to as Gulf Blue, presents significant accessibility challenges. Its very dark hue results in extremely low contrast against typical light backgrounds like white or light gray. This low contrast makes text and other visual elements difficult to discern for users with visual impairments, including those with low vision or color blindness. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Gulf Blue against a white background falls far short of these recommendations. To improve accessibility, it is strongly advised to pair this color with very light colors like white, yellow, or very bright green to meet the contrast requirements, or to limit its use to purely decorative elements where legibility is not critical.
