General Information about Gulf Blue (#040459)

The hex color #040459, also known as Gulf Blue, is a very dark shade of blue. In the RGB color model, it is composed of 1.57% red, 1.57% green, and 34.9% blue. This composition results in a color that is perceived as deep, subdued, and somewhat mysterious. Gulf Blue belongs to the blue color family, which is often associated with feelings of calmness, stability, and trust. However, due to its very low saturation and high darkness, #040459 can also evoke feelings of sadness or seriousness. In terms of color theory, #040459's low brightness makes it challenging to use as a primary color but highly suitable for creating depth and contrast when paired with brighter, lighter hues. It is widely used in various applications, ranging from web design to interior decoration.

The hex color #040459, also known as Gulf Blue, presents significant accessibility challenges, especially in text applications. Its extremely low luminance value makes it difficult to achieve sufficient contrast against lighter backgrounds, such as white or pale yellow. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text. This dark blue shade would likely fail these contrast tests with many commonly used background colors. To improve accessibility, consider using #040459 sparingly, primarily for decorative elements rather than essential information. When using it for text or interactive elements, pair it with very light colors or use techniques like color overlays or shadows to enhance contrast. Thoroughly testing with accessibility evaluation tools is crucial to ensure readability and usability for users with visual impairments.
