About Ultramarine (#0C148C)

Ultramarine, represented by the hex code #0C148C, is a deep blue color with a rich history. The name "Ultramarine" originates from the Latin "ultramarinus," meaning "beyond the sea," as the pigment was originally imported from mines in Afghanistan by sea. Historically, it was derived from the semi-precious stone lapis lazuli, making it one of the most expensive and prized pigments. The modern Ultramarine is a synthetic pigment with the chemical formula Na₈₋₁₀Al₆Si₆O₂₄S₂₋₄. It is known for its exceptional lightfastness, color stability, and resistance to alkali. It is widely used in paints, plastics, cosmetics, and other applications requiring a vibrant and durable blue hue. The color is known for its association with royalty, sophistication, and wisdom.

The color #0C148C, also known as Ultramarine, presents some accessibility challenges, particularly concerning color contrast. When used as a background color, it's crucial to select text colors that provide sufficient contrast to ensure readability for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Light shades of yellow or white would likely offer the best contrast against the deep blue hue of Ultramarine. Careful consideration should also be given to interactive elements like buttons and links, ensuring they are clearly distinguishable and provide sufficient visual feedback upon interaction. Additionally, avoid using color as the sole means of conveying information; supplement it with text labels or icons to accommodate users with color blindness. Providing alternative text descriptions for images and other non-text content is also essential for accessibility.
