About Ultramarine

Ultramarine, represented by the hexadecimal color code #19108B, is a deep blue pigment originally derived from the precious mineral lapis lazuli. Its name literally means "beyond the sea," reflecting its historical import from overseas. This color has been highly valued since the Middle Ages, used extensively in illuminated manuscripts and Renaissance paintings. In modern color theory, Ultramarine is considered a primary color and is frequently employed in various artistic and design applications. The pigment's chemical composition primarily consists of sodium aluminosilicate with sulfur, giving it its characteristic intense blue hue. Today, synthetic versions of Ultramarine are widely available, offering the same vibrant color at a more accessible price point.

The hex color #19108B, also known as Ultramarine, presents significant accessibility challenges, especially concerning text legibility. Due to its dark hue, it demands careful consideration of contrast ratios. When used as a background color, it necessitates light-colored text to ensure readability for individuals with visual impairments. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text, as per WCAG guidelines. Insufficient contrast can render content inaccessible to users with low vision or color blindness. Moreover, relying solely on color to convey information is discouraged. Supplementing color cues with text labels or icons enhances accessibility for all users, including those who may not perceive color accurately. Thoroughly testing color combinations with accessibility evaluation tools is essential to validate conformance to accessibility standards.
