General Information about Ultramarine

The hex color #1B04B0, commonly known as Ultramarine, is a deep and intense shade of blue. It belongs to the blue color family and is characterized by its strong saturation and relatively low brightness. Ultramarine has a rich history, originally derived from the precious gemstone lapis lazuli. In art and design, Ultramarine is often associated with royalty, spirituality, and depth. It is used to evoke feelings of trust, stability, and sophistication. This color is frequently employed in branding, web design, and interior decoration to create a sense of elegance and authority. Due to its intensity, Ultramarine is often used as an accent color rather than a primary color.

The hex color #1B04B0, also known as Ultramarine, presents significant accessibility challenges, especially in text-based applications. Its dark hue results in a low contrast ratio against typical light backgrounds (like white or light gray). This can make text difficult to read for individuals with visual impairments, including those with low vision or color blindness. To improve accessibility, it's crucial to use #1B04B0 sparingly for text and to pair it with very light colors to ensure sufficient contrast. For graphical elements or backgrounds, consider providing alternative visual cues, such as shapes or patterns, to convey information in addition to color. Adhering to WCAG (Web Content Accessibility Guidelines) contrast ratio standards is essential when using this color to ensure inclusivity.
