General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #1A0B90, is a deep, rich blue color. It belongs to the blue color family and is known for its intense and vibrant hue. In the RGB color model, it is composed of 10.2% red, 4.3% green, and 56.5% blue. This particular shade of blue is often associated with feelings of depth, stability, and wisdom. Historically, Ultramarine was derived from the precious stone lapis lazuli, making it a highly valued pigment in art. Its name literally means "beyond the sea," reflecting its origin as a pigment imported from Asia. Today, synthetic ultramarine is widely available, making it more accessible for various applications.

The color #1A0B90, also known as Ultramarine, presents some accessibility challenges. Its low lightness value (approximately 6%) means that it requires very light text colors to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using white text (#FFFFFF) on a background of #1A0B90 achieves a high contrast ratio, meeting accessibility standards. However, avoid using darker shades or colors with similar lightness values as text, as this would result in insufficient contrast, making it difficult for users, especially those with visual impairments, to read the content. When using this color, carefully consider its impact on users with color blindness, ensuring that crucial information isn't solely conveyed through color.
