General Information about Ultramarine

Ultramarine, represented by the hex code #030598, is a deep, intense blue color historically derived from the precious mineral lapis lazuli. The name 'ultramarine' literally means 'beyond the sea,' reflecting its origin as a pigment imported to Europe from mines in Asia. Chemically, the modern pigment is a complex sodium aluminum silicate with sulfur. Known for its rich and vibrant hue, ultramarine has been highly valued by artists throughout history, particularly during the Renaissance. Its stability and lightfastness have made it a preferred choice for creating enduring artworks. Today, synthetic ultramarine is widely available, offering the same beautiful color at a more affordable price. Its enduring popularity lies in its depth, clarity, and the sense of luxury it evokes.

The hex color #030598, also known as Ultramarine, presents significant accessibility challenges due to its very low luminance. When used as a foreground color against a white or light background, the contrast ratio is critically low, making it difficult for individuals with visual impairments to discern text or graphical elements. To improve accessibility, it is crucial to pair this dark blue hue with very light colors, such as white (#FFFFFF) or a pale yellow (#FFFFE0), to ensure sufficient contrast. The Web Content Accessibility Guidelines (WCAG) recommend a contrast ratio of at least 4.5:1 for standard text and 3:1 for large text. Using tools to measure contrast ratios is essential before deploying this color in user interfaces. Consider alternative, lighter shades of blue if maintaining the exact hue is not critical for branding or design purposes. Proper color choices are vital for inclusivity and ensuring a positive user experience for everyone.
