General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #0D118A, is a deep and intense shade of blue. Historically, ultramarine was derived from the rare and precious mineral lapis lazuli, making it one of the most expensive pigments during the Middle Ages and Renaissance. Today, synthetic ultramarine is widely available, retaining the original's rich and vibrant hue. This color is associated with qualities such as wisdom, trust, and stability, making it a popular choice across various applications. In color psychology, it is often linked to feelings of calmness, order, and introspection. Ultramarine finds usage in branding, graphic design, and fine arts due to its visual appeal and psychological associations.

The color #0D118A, also known as Ultramarine, presents some accessibility challenges, particularly for users with visual impairments. Due to its dark hue, the contrast ratio against a standard white background is low, which can make text or interactive elements difficult to read. Web developers should ensure sufficient contrast by pairing it with significantly lighter colors, such as shades of white, cream, or very light yellows. Using contrast ratio tools can help determine compliance with WCAG guidelines. Additionally, avoid using this color as the sole indicator of important information; supplement it with text labels, icons, or other visual cues to ensure usability for all users, including those with color blindness. Thoughtful design practices will enhance the inclusivity of digital content.
