General Information about Gulf Blue

#0A1B5A, also known as Gulf Blue, is a deep, saturated shade of blue that evokes feelings of sophistication, depth, and tranquility. It is created by combining a small amount of red and green with a dominant amount of blue in the RGB color model. In the CMYK color model, it consists primarily of cyan, magenta and black. This color can be used to represent both the depth of the sea and the vastness of the night sky. This hexadecimal code translates to 10 red, 27 green, and 90 blue in the RGB color space. Colors similar to Gulf Blue may include navy, midnight blue, and other deep blue variations, though each will have its unique tonal qualities. Gulf Blue's particular depth and saturation make it a versatile choice for creating a sense of both stability and elegance.

The hex color #0a1b5a, also known as Gulf Blue, presents some accessibility challenges, particularly concerning color contrast. When used as a background color, it requires light text for readability. The contrast ratio should be at least 4.5:1 for normal text and 3:1 for large text, as per WCAG guidelines. Using a color contrast checker is highly recommended to ensure compliance. Given its darkness, pairing #0a1b5a with very light shades of yellow, white, or even light cyan can improve legibility for users with visual impairments. When used for interactive elements such as buttons or links, ensure sufficient visual cues beyond color alone are provided, such as underlines or borders, to accommodate users with color blindness. Careful consideration of these aspects will help make digital content more accessible and inclusive.
