Gulf Blue

#0A0A50

General Information about #0A0A50

The hexadecimal color code #0A0A50 represents a dark shade of blue, often referred to as 'Gulf Blue' due to its resemblance to the deep ocean. It is composed of 3.92% red, 3.92% green, and 31.37% blue. In the RGB color model, this translates to 10 red, 10 green, and 80 blue. This color is best used as an accent due to its darkness, and works best when paired with lighter colors. The color is also commonly used to convey a sense of stability, trust, and sophistication. Because the human eye is more sensitive to greens, the low green level of 3.92% contributes to its deep blue tone, making it visually rich but potentially challenging for accessibility if not used carefully.

The color #0A0A50, also known as Gulf Blue, presents significant accessibility challenges, especially in web design. Its extremely low lightness value results in very poor contrast against standard white backgrounds. This lack of contrast makes it difficult for users with visual impairments, such as those with low vision or color blindness, to read text or distinguish interface elements. According to WCAG guidelines, sufficient contrast is crucial for accessibility. To improve accessibility, consider using a much lighter color for text or interactive elements against a #0A0A50 background, or conversely, use #0A0A50 for text on a very light background. Testing with accessibility tools is highly recommended to ensure compliance with accessibility standards and provide an inclusive user experience. Using tools such as contrast checkers help assess and rectify any accessibility issues.
