#00045D

General Information

The hexadecimal color code #00045D, also known as Gulf Blue, signifies a very dark shade of blue, nearing black. It is composed of 0% red, 1.6% green, and 36.5% blue. In the RGB color space, this equates to R:0, G:4, B:93. Its CMYK representation is C:1, M:0.96, Y:0, K:0.64. This color evokes feelings of depth, sophistication, and formality. Due to its darkness, it is rarely used as a primary color but is often employed as an accent to add a touch of elegance or create contrast with lighter hues. Gulf Blue is often associated with corporate branding, luxury goods, and nautical themes, where its depth and richness can be effectively utilized.

The hex color #00045d, also known as Gulf Blue, presents significant accessibility challenges, particularly in text-based applications. Its extremely low luminance value (very close to black) results in poor contrast against standard light backgrounds (like white or light gray). This fails to meet WCAG (Web Content Accessibility Guidelines) requirements for contrast ratios, specifically Success Criterion 1.4.3 (Contrast Minimum). To ensure readability, this color should strictly be paired with very light shades, such as yellows or near-white colors, to provide sufficient contrast. When using #00045d for non-text elements, consider its impact on users with visual impairments, and provide alternative visual cues to convey the same information. Thorough testing with accessibility tools and diverse user groups is crucial to validate its suitability in any design.
