General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #1207AD, is a deep blue pigment historically made by grinding lapis lazuli into a powder. The name 'Ultramarine' comes from the Latin 'ultramarinus,' meaning 'beyond the sea,' as the pigment was imported into Europe from Asia. Chemically, Ultramarine is a complex sodium aluminosilicate with sulfur. It is prized for its intense and pure blue hue, making it a staple in art and design. In modern times, synthetic Ultramarine is produced, offering a more affordable and consistent alternative to the natural pigment. It is used extensively in paints, plastics, cosmetics, and even laundry detergents to enhance whiteness. Ultramarine is considered a cool color that has a calming and relaxing effect.

The color #1207AD, Ultramarine, presents some accessibility challenges, particularly concerning color contrast. When using this color for text, it's crucial to ensure sufficient contrast with the background. A light or white background is highly recommended to improve readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text. Using online contrast checker tools, web developers can verify whether chosen color pairings meet these standards. Also, avoid using this color as the sole indicator of important information; supplement it with text labels or icons to ensure accessibility for users with color vision deficiencies. Providing alternative color themes or allowing users to customize colors can further enhance the accessibility of web content utilizing Ultramarine.
