#180DA7

General Information about Ultramarine

Ultramarine, represented by the hex code #180DA7, is a deep and intense shade of blue historically derived from the precious mineral lapis lazuli. The name itself means 'beyond the sea,' reflecting its origin as an imported pigment. Known for its exceptional richness and non-fading qualities, ultramarine was highly valued by Renaissance artists, who reserved it for important figures and details in their paintings. Today, synthetic ultramarine is widely available, offering the same vibrant hue at a more affordable cost. In color theory, ultramarine sits between blue and violet, exhibiting a calming yet sophisticated presence. Its deep tone adds a touch of elegance and depth to various applications, including design and fashion.

The color #180DA7, also known as Ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its dark hue results in a low contrast ratio against lighter backgrounds, making text and interface elements difficult to read. According to WCAG guidelines, sufficient contrast is crucial for readability. To improve accessibility, consider pairing Ultramarine with very light colors such as white (#FFFFFF) or very light grays. Using larger font sizes or adding a text shadow can also help. For decorative elements, ensure that crucial information isn't solely conveyed through color. When used as a background, light text is preferable, and interactive elements need clear visual cues besides color alone to indicate their function. Thorough testing with accessibility tools is essential to ensure compliance and a positive user experience for everyone.
