General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #0D11A7, is a deep and rich blue hue. Historically, ultramarine was derived from the semi-precious stone lapis lazuli, making it a highly prized and expensive pigment used primarily by Renaissance painters. The name 'ultramarine' literally means 'beyond the sea,' reflecting its origin from pigments imported into Europe from Asia. In modern times, synthetic ultramarine is widely available, offering the same vibrant color at a fraction of the cost. This color is associated with depth, stability, and authority, making it a popular choice for branding and design where trustworthiness and reliability are desired. It is a dark shade of azure.

The color #0D11A7, a deep ultramarine, presents accessibility challenges due to its low luminance. When used as text, it requires high contrast against light backgrounds to ensure readability for individuals with visual impairments. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text, as per WCAG guidelines. Avoid pairing it with dark backgrounds. When used for interactive elements, sufficient contrast must be maintained to ensure users can distinguish these elements. Additionally, provide alternative cues such as text labels or icons to enhance usability for users who may have difficulty perceiving color differences. Using a color contrast checker tool is advised to verify compliance with accessibility standards. Consider using a lighter tint of ultramarine or a completely different color palette to improve overall accessibility.
