#140D8A

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #140d8a, is a deep, rich shade of blue. It derives its name from the Latin "ultramarinus," meaning "beyond the sea," as the pigment was originally imported from Asia. Historically, ultramarine was produced from the precious gemstone lapis lazuli, making it one of the most expensive and highly prized pigments. Its use was often reserved for the most important figures and elements in paintings, particularly in religious art to depict the robes of the Virgin Mary. Today, synthetic ultramarine is widely available, offering the same vibrant color at a fraction of the cost. This color evokes feelings of calmness, depth, and sophistication.

The hex color #140d8a, also known as Ultramarine, presents several accessibility considerations for web developers. Its dark shade 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, including those with low vision or color blindness. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Therefore, pairing #140d8a with lighter colors like whites, creams, or light yellows is essential to ensure readability and usability. Additionally, avoid using color as the sole means of conveying information; incorporate text labels or icons to provide alternative cues for users who may not be able to distinguish the color. Thoughtful design choices can significantly enhance the inclusivity of web content, making it accessible to a broader audience.
