General Information about #1B118A (Ultramarine)

The hex color #1B118A, also known as Ultramarine, is a deep shade of blue that evokes feelings of sophistication, depth, and tranquility. It is created by combining a small amount of red and green with a dominant amount of blue in the RGB color model. In the world of color theory, Ultramarine is often associated with intelligence, stability, and unity. Historically, the pigment ultramarine was derived from lapis lazuli, making it a highly valued and expensive color, often reserved for royalty and religious figures. Today, it is widely available and used across various mediums, from digital art to physical paints. It's essential to consider its context, as its darkness can impact accessibility if not paired with appropriate contrasting colors.

The color #1B118A, a deep ultramarine, presents accessibility challenges due to its low luminance. When used as text, it requires a very light background to meet WCAG standards for contrast ratio, ensuring readability for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When used as a background color, ensure that the foreground text is sufficiently light. Avoid using this color for small text or crucial interface elements without careful consideration of contrast. Providing alternative high-contrast themes or allowing users to adjust color settings can enhance accessibility. Additionally, avoid using color alone to convey important information; supplement it with text or icons.
