General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #010098, is a deep, rich blue color reminiscent of the precious pigment derived from lapis lazuli. Historically, Ultramarine was highly valued and expensive, making it a color reserved for royalty and significant artistic works. In the RGB color model, Ultramarine is composed of 0.4% red, 0% green, and 59.6% blue. Its CMYK values are 99% cyan, 100% magenta, 0% yellow, and 63% black. The color's darkness and high blue component contribute to its association with depth, stability, and sophistication. Today, synthetic Ultramarine is widely available, making it accessible for various applications in art, design, and technology. Its unique hue continues to evoke a sense of luxury and timeless elegance.

The hex color #010098, also known as Ultramarine, presents significant accessibility challenges, particularly in web design. Its very low luminance value makes it difficult to read when used as text against a white or light-colored background. According to WCAG guidelines, sufficient contrast between text and background is crucial for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Ultramarine, due to its darkness, often fails to meet these ratios unless paired with a very light color like white or a pale yellow. When using this color, developers should conduct thorough contrast checks using online tools or accessibility testing software. Consider alternatives or modifications to ensure readability and inclusivity. Using Ultramarine sparingly, perhaps for decorative elements rather than essential text, can help mitigate accessibility issues. Always prioritize user experience by providing sufficient contrast and ensuring content is perceivable by everyone, including individuals with disabilities.
