General Information about Ultramarine

The hexadecimal color #010A97, also known as Ultramarine, is a deep, saturated blue. It is composed of 0.4% red, 3.92% green, and 59.22% blue. In the RGB color space, it signifies a strong emphasis on the blue component, creating a dark and intense hue. Ultramarine has a rich history, originally derived from the precious mineral lapis lazuli, making it a highly valued pigment in art for centuries. Its name literally means 'beyond the sea,' reflecting its import from distant lands. Today, synthetic ultramarine is widely available, offering the same vibrant color at a more accessible price. This color is often associated with depth, stability, and authority.

The color #010A97, a deep ultramarine, presents accessibility challenges, especially when used as a foreground color on a white or light background. Its low luminance necessitates careful consideration of color contrast ratios to ensure readability for users with visual impairments. According to WCAG guidelines, sufficient contrast is crucial for text and interactive elements. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using #010A97 on a white background may not meet these standards, requiring designers to either lighten the color, choose a different hue, or employ a lighter foreground color such as white or a very light gray to achieve adequate contrast. Also, when using this color for links, provide additional cues like underlines to help users with color blindness identify interactive elements. Careful attention to these factors is essential to create an inclusive and accessible web experience. Consider tools that check color contrast to ensure compliance.
