General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #19159F, is a deep blue pigment originally derived from the mineral lapis lazuli. Its name originates from the Latin 'ultramarinus,' meaning 'beyond the sea,' as the pigment was imported into Europe from Asia. Chemically, it is a complex sodium aluminosilicate with sulfur. Known for its rich, intense color and excellent lightfastness, Ultramarine has been highly valued throughout history by artists and painters. In modern times, synthetic Ultramarine is widely produced, offering the same vibrant hue at a lower cost. The color is associated with royalty, intellect, and spirituality. In digital applications, #19159F can evoke feelings of trust, authority, and depth.

The color #19159F, a deep Ultramarine, presents specific accessibility considerations, especially in web design. When used as a background, it requires careful selection of foreground text color to ensure sufficient contrast. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. Using white or very light shades of yellow or green as the foreground text color can improve readability. Additionally, avoid using this color for essential visual elements if users cannot differentiate colors, which could impact usability for color-blind users. Providing alternative visual cues, such as text labels or icons, can help mitigate accessibility issues. It's important to test color combinations using accessibility evaluation tools to ensure compliance with accessibility standards.
