Ultramarine

#16159B

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #16159B, is a deep blue pigment originally derived from the mineral lapis lazuli. Its name literally means 'beyond the sea,' reflecting its historical import from regions east of Europe. Revered for its intense and vibrant hue, ultramarine has been prized by artists for centuries, featuring prominently in iconic works of art, particularly during the Renaissance. Chemically, it is a complex sodium aluminum silicate with sulfur, responsible for its distinctive color. Today, synthetic ultramarine is widely available, offering a more affordable alternative to the natural pigment while maintaining its captivating aesthetic appeal. The color evokes feelings of serenity, wisdom, and depth, and is often associated with royalty and spirituality.

The color #16159B, a deep ultramarine, presents significant accessibility challenges, primarily due to its low luminance. When used as a background color, it necessitates very light text to achieve sufficient contrast for readability, ideally a white or near-white shade. Conversely, if used for text, a very light background is crucial. Web Content Accessibility Guidelines (WCAG) recommend specific contrast ratios (4.5:1 for normal text and 3:1 for large text) to ensure usability for individuals with visual impairments. Tools like contrast checkers can verify compliance. Furthermore, avoid relying solely on color to convey information, as users with color vision deficiencies may not perceive the intended meaning. Provide redundant cues, such as text labels or icons, to enhance accessibility. Thoughtful consideration of color choices is vital for creating inclusive and user-friendly web experiences.
