General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #0D118F, is a deep, rich shade of blue. Historically, ultramarine was derived from the rare and expensive mineral lapis lazuli, making it a highly prized pigment used in paintings and decorative arts. Its name literally means "beyond the sea," referring to its origin from lands east of Europe. In modern color theory, ultramarine is considered a cool color, associated with calmness, depth, and stability. It is often used to evoke feelings of trust, loyalty, and authority. In digital design, the hex code #0D118F allows for precise color reproduction across various devices and platforms, ensuring consistency in branding and visual communication. While visually appealing, the dark nature of ultramarine requires careful consideration of contrast ratios to ensure accessibility in user interfaces and designs.

The color #0D118F, also known as Ultramarine, presents significant accessibility challenges, particularly concerning color contrast. When used as text against a white background, the contrast ratio is very low, making it difficult for individuals with visual impairments to read. To improve accessibility, it is crucial to pair this color with much lighter shades for text or interactive elements. A lighter background or text color will ensure that users with low vision or color blindness can perceive the content effectively. Tools like contrast checkers can help web developers and designers determine if their color combinations meet accessibility standards, such as WCAG guidelines. It is best to avoid using this color for critical information or actions without proper contrast adjustments.
