#11099D

General Information about Ultramarine

Ultramarine, represented by the hex code #11099D, is a deep blue color historically derived from the precious mineral lapis lazuli. The name "ultramarine" literally means "beyond the sea," reflecting the fact that the pigment was imported into Europe from mines in Asia. This color is known for its intense and vibrant hue, making it a popular choice in various art forms throughout history. In modern color theory, Ultramarine is classified as a cool color, often associated with feelings of calmness, depth, and stability. Its high saturation level allows it to stand out and create a focal point in designs. However, its darkness requires careful consideration when paired with other colors to ensure readability and visual balance.

The hex color #11099D, also known as Ultramarine, presents significant accessibility challenges, primarily due to its dark hue. When used as a background color, it necessitates very light text to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between the text and background should be at least 4.5:1 for normal text and 3:1 for large text. This color may not meet these ratios with moderately dark or gray text. It is essential to test color combinations using accessibility evaluation tools to avoid visual strain and ensure that content is accessible to users with visual impairments. Using a lighter tint of Ultramarine or pairing it with contrasting colors like yellow or white can improve accessibility. Furthermore, avoid using this color for critical UI elements without careful consideration of the contrast.
