General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #0B0F90, is a deep and intense shade of blue. Historically, the term 'ultramarine' refers to a pigment derived from lapis lazuli, a rare and highly valued stone. This pigment was highly prized by Renaissance painters for its vibrant and lasting color, often used to depict the robes of the Virgin Mary or other figures of importance. Today, synthetic ultramarine pigments offer a more affordable and accessible alternative, retaining the same rich hue. In color theory, ultramarine sits firmly within the blue family, evoking feelings of depth, stability, and tranquility. Its intensity and darkness make it suitable for creating a sense of drama and sophistication in design and art.

The hex color #0B0F90, also known as Ultramarine, presents significant accessibility challenges, particularly in web design. Its very dark hue results in low contrast when paired with other dark colors, making text or interface elements difficult to read for users with visual impairments. Adhering to WCAG (Web Content Accessibility Guidelines) standards is crucial. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended. Using this color for text on a white background might barely pass the minimum contrast requirements, but it's far from ideal. Therefore, avoid using this color for text or important interactive elements unless paired with a very light color to ensure sufficient contrast. Consider using color contrast analyzers to verify compliance and improve the overall user experience for individuals with disabilities.
