General Information about Gulf Blue

The hexadecimal color code #040B53, also known as Gulf Blue, represents a dark shade of blue. It is composed of 1.57% red, 4.31% green, and 32.55% blue. In the RGB color model, this translates to 4 red, 11 green, and 83 blue. The CMYK representation is 95% cyan, 87% magenta, 0% yellow, and 67% black. This color is often associated with depth, sophistication, and mystery. Given its low luminance, it is generally not recommended for use as a primary text color, especially on light backgrounds, due to accessibility concerns regarding contrast. However, it can be effectively used as an accent color or background element to create a sense of elegance and depth in designs. Always evaluate the context and purpose of the color within a composition.

The hex color #040B53, also known as Gulf Blue, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low luminance value of 0.005 makes it difficult to achieve sufficient contrast with lighter text or background elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using #040B53 for text on a white background (or vice versa) would result in a contrast ratio far below these recommendations. Therefore, it's crucial to avoid using this color for essential text or interactive elements without careful consideration. If you must use #040B53, pair it with very light colors like #FFFFFF or consider increasing the font size and weight to improve readability. Providing alternative text descriptions for images and other non-text content is also essential to ensure accessibility for all users.
