General Information about Ultramarine

Ultramarine, represented by the hex code #0c188f, is a deep blue color with a rich history. Derived from the Latin 'ultramarinus', meaning 'beyond the sea,' it originally referred to pigment made from lapis lazuli imported from Asia. This pigment was highly prized in the Middle Ages and Renaissance, often reserved for the most important figures in paintings, such as the Virgin Mary. The color conveys feelings of depth, stability, and trust, and is often associated with royalty and wisdom. In modern color psychology, Ultramarine is still seen as a sophisticated and authoritative color, making it a popular choice for corporate branding and design. Its high blue component evokes a sense of calm and security. It is not often found in nature and must be manufactured.

The hex color #0c188f, also known as Ultramarine, presents some accessibility challenges, particularly regarding text contrast. When used as a background color, careful consideration must be given to the foreground text color to ensure readability. According to WCAG guidelines, sufficient contrast ratios are crucial for users with visual impairments. A light text color, such as white or a very pale yellow, is highly recommended to achieve an acceptable contrast ratio of at least 4.5:1 for standard text and 3:1 for large text. Avoid using dark text colors on this background, as they will likely be difficult to read. Also, consider providing alternative visual cues, such as borders or icons, to enhance usability for users who may have difficulty distinguishing colors. Testing the color combination with accessibility evaluation tools is strongly advised.
