General Information

The hex color #00035B, also known as Gulf Blue, is a deep, dark shade of blue with a high level of saturation. In the RGB color model, it is composed of 0% red, 1.2% green, and 35.7% blue. This composition creates a color that is both intense and somber, evoking feelings of depth, stability, and even a hint of mystery. The color is far from the primary blue tone, having a deeper, more muted character due to its low red and green components.

In branding, it can represent trust and security, making it a popular choice for financial institutions and corporate entities seeking to project a sense of reliability.

The hex color #00035B, a deep, saturated blue, presents significant accessibility challenges. Its very low luminance value means it provides insufficient contrast against lighter backgrounds, making text or interactive elements difficult to read for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. This color is highly unlikely to meet these ratios against most background colors. To improve accessibility, it should be paired with very light colors, and even then, careful testing with accessibility evaluation tools is essential to ensure compliance. Developers should also consider providing alternative color schemes that offer better contrast for users with different visual needs. The use of this color should be limited to decorative elements where readability is not essential. Use of color alone to convey information should also be avoided.
