General Information about Gulf Blue

The color #02045B, commonly referred to as Gulf Blue, is a deep, dark shade of blue within the broader blue color family. It is characterized by a minimal presence of red and green, resulting in a strong, concentrated blue hue. In the RGB color model, which is used for digital displays, #02045B is composed of 0.8% red, 1.6% green, and 35.7% blue. In the CMYK color model, used for printing, it consists of 98% cyan, 93% magenta, 0% yellow, and 64% black. This combination ensures a rich, saturated blue that can be reproduced accurately in both digital and print media. Gulf Blue evokes feelings of calmness, stability, and trustworthiness, making it a popular choice for branding and design contexts where these qualities are desired.

The hex color #02045B, also known as Gulf Blue, presents significant accessibility challenges, especially when used for text or interactive elements. Its extremely low luminance value of approximately 0.002 makes it difficult to achieve sufficient contrast against lighter 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 is unlikely to meet these ratios with any but the lightest shades of white or yellow. Therefore, it is strongly recommended to avoid using Gulf Blue for text, icons, or other essential visual elements unless paired with a very light color and carefully tested for accessibility. When using Gulf Blue, consider providing alternative high-contrast themes or allowing users to customize the color scheme to meet their individual needs. Tools like contrast checkers can help determine if the color combination meets accessibility standards.
