General Information about Ultramarine (#1C0497)

The color #1C0497, commonly known as Ultramarine, is a deep, rich shade of blue. Historically, ultramarine was derived from the precious gemstone lapis lazuli, making it a highly valued pigment used by Renaissance painters and associated with royalty and divinity. Today, synthetic ultramarine is widely available, retaining the characteristic depth and intensity of the original pigment. In color theory, ultramarine is considered a cool color, evoking feelings of calmness, stability, and sophistication. It is often associated with intelligence, trust, and efficiency. Due to its dark value, it should be used carefully in design, often requiring contrasting elements to ensure readability and visual balance. Its hex code #1C0497 indicates a composition primarily of blue light, with minimal red and green components, resulting in its distinctively deep blue appearance.

The color #1C0497, a deep ultramarine, presents several accessibility considerations for web developers. Its low lightness value (approximately 10%) means it offers poor contrast against standard white backgrounds, potentially causing readability issues for users, especially those with visual impairments. To ensure accessibility, it is crucial to use sufficiently light text colors on this background, adhering to WCAG guidelines for contrast ratios. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Tools like contrast checkers can help determine appropriate color pairings. Avoid using this color for small text or critical interactive elements without careful contrast consideration. Furthermore, when used as a background for links, ensure that link states (hover, focus, visited) are clearly distinguishable, ideally through color changes or other visual cues. The use of ARIA attributes can also enhance the accessibility of elements using this color.
