General Information about Ultramarine

Ultramarine, represented by the hex code #0B1390, is a deep and intense shade of blue. Historically, ultramarine was derived from the precious gemstone lapis lazuli, making it one of the most expensive and highly valued pigments. The name "ultramarine" literally means "beyond the sea," reflecting its origin from stones imported into Europe from distant lands. Today, synthetic ultramarine is widely available, retaining the same vibrant and rich color without the exorbitant cost. This color is often associated with depth, stability, and sophistication. In color psychology, blue is often linked to feelings of trust, peace, and order. Therefore, ultramarine can be a great option for branding and design where these qualities are desired.

The hex color #0B1390, also known as Ultramarine, presents several accessibility considerations for web developers. Its dark hue necessitates careful attention to color contrast ratios, especially when used for text or interactive elements. According to WCAG guidelines, sufficient contrast between foreground and background colors is crucial for users with visual impairments to perceive content effectively. A light color must be used when this color is used as background color. It is recommended to use tools to assess the contrast ratio and ensure it meets at least the AA standard (4.5:1 for normal text and 3:1 for large text). Additionally, consider providing alternative cues, such as icons or text labels, alongside color to convey information, as color blindness affects a significant portion of the population. Thoughtful use of ARIA attributes can also enhance the accessibility of components using this color, by providing screen readers with additional context and semantic information. Proper testing with assistive technologies is vital to confirm usability for all users.
