General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #040F94, is a deep, rich shade of blue reminiscent of the pigment derived from lapis lazuli. Its name literally means "beyond the sea," originating from the pigment's historical import from Asia to Europe. Chemically, the modern pigment is a complex sodium aluminosilicate with sulfur. Ultramarine's intense color is due to the presence of polysulfide ions within the crystal lattice. It is known for its excellent lightfastness and stability, making it a preferred choice in various applications, including fine art, cosmetics, and plastics. This color evokes feelings of serenity, depth, and sophistication, and can be associated with royalty and intelligence. Its depth makes it well-suited for creating a sense of formality and trust.

The color #040F94, also known as Ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its dark hue results in a low contrast ratio against lighter backgrounds, making text and other visual elements difficult to discern. To ensure inclusivity, it's crucial to use this color sparingly, especially for text or interactive elements. When using Ultramarine, always pair it with a very light background to meet WCAG (Web Content Accessibility Guidelines) contrast ratio requirements. Consider providing alternative high-contrast themes or user-adjustable color settings to accommodate individuals with diverse visual needs. Careful attention to color contrast is paramount to delivering an accessible and user-friendly experience for everyone, including those with low vision or color blindness. Avoid using it for important visual cues without providing redundant indicators.
