Ultramarine

#031195

General Information about Ultramarine

Ultramarine, represented by the hex code #031195, is a deep, intense shade of blue. Historically, ultramarine was derived from the precious mineral lapis lazuli, making it one of the most expensive and highly prized pigments. The name 'ultramarine' literally means 'beyond the sea,' referring to its origin from stones imported into Europe from Asia. Today, synthetic ultramarine is widely available, offering the same vibrant hue at a fraction of the cost. This color is often associated with royalty, intelligence, and depth. In art, ultramarine has been used by masters such as Vermeer and Raphael to create stunning effects of light and shadow, adding richness and realism to their works.

The hex color #031195, a deep ultramarine, presents significant accessibility challenges, particularly in web design. Its extremely low luminance value necessitates careful consideration of color contrast ratios to ensure readability and usability for individuals with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text against its background. Using #031195 for text on a white background would fall far short of these recommendations. To improve accessibility, consider using lighter text colors such as white or very light grays. Alternatively, #031195 can be paired with much lighter background colors, but testing with accessibility tools is still recommended to verify compliance. Avoid using this color for crucial interface elements or information without sufficient contrast, as it can render content inaccessible to many users.
