General Information about Gulf Blue

The hex color #010556, also known as Gulf Blue, is a dark shade of blue that resides within the blue-violet color space. It has a very low red component (1/255), a slightly higher green component (5/255), and a substantial blue component (86/255), resulting in its deep, rich hue. In the RGB color model, it's composed of 0.39% red, 1.96% green, and 33.73% blue. When converted to the CMYK color model, it consists of 99% cyan, 94% magenta, 0% yellow, and 66% black. This color is often associated with feelings of depth, stability, and sophistication. It can be used to evoke a sense of trust and authority, making it a popular choice for corporate branding. The low lightness value of this color makes it unsuitable for use as a primary text color on light backgrounds; however, it can be effectively used as an accent color or as a background color for light text.

The hex color #010556, also known as Gulf Blue, presents considerable accessibility challenges, particularly in text-based applications. Its extremely low lightness value (close to black) means that it offers very poor contrast against standard white backgrounds. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text to ensure readability for users with moderate visual impairments. Gulf Blue falls far short of these recommendations. To improve accessibility, it is strongly advised to pair it with very light colors such as white, light gray, or pale yellow. Additionally, when using this color for interactive elements like buttons or links, sufficient visual cues beyond color alone should be provided to assist users who may have color vision deficiencies. Using patterns, underlines, or other indicators in conjunction with color can significantly enhance the usability of content for a wider audience. Careful consideration of contrast and redundant coding practices are essential when incorporating such a dark hue into any design.
