#050098

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #050098, is a deep, intense shade of blue. Historically, Ultramarine was derived from the rare and precious mineral lapis lazuli, making it a highly valued pigment, particularly in Renaissance paintings. Its name literally means 'beyond the sea,' referring to its origin from overseas sources. In the RGB color model, #050098 consists of 2% red, 0% green, and 60% blue. This high blue component is what gives Ultramarine its characteristic deep blue hue. In the CMYK color model, it comprises 95% cyan, 100% magenta, 0% yellow, and 62% black. This color is often associated with royalty, wisdom, and spirituality. Its usage in art and design can evoke feelings of depth, sophistication, and tranquility. However, due to its dark nature, it requires careful consideration when used in design to ensure adequate contrast and accessibility.

The hex color #050098, also known as Ultramarine, presents significant accessibility challenges, particularly in web design. Its extremely dark hue results in very low contrast against standard light backgrounds, such as white (#FFFFFF). This fails to meet the minimum contrast ratios recommended by the Web Content Accessibility Guidelines (WCAG) for text and interactive elements. Specifically, WCAG 2.1 level AA requires a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text and user interface components. Using #050098 for text on a white background would not provide sufficient contrast, making it difficult for users with visual impairments, including those with low vision or color blindness, to read the content. To improve accessibility, it's crucial to pair #050098 with a much lighter color, aiming for a contrast ratio that meets or exceeds WCAG guidelines. Tools like contrast checkers can help designers ensure their color choices are accessible to all users. Alternatively, avoid using #050098 for text or important UI elements unless paired with a highly contrasting color to ensure readability and usability.
