General Information about Ultramarine (#1D0197)

The color #1D0197, also known as Ultramarine, is a deep and intense shade of blue. It is characterized by its rich, almost violet undertones, giving it a luxurious and sophisticated appearance. Historically, ultramarine pigment was derived from the semi-precious stone lapis lazuli, making it highly valued and expensive. This association with rarity and prestige has contributed to its perception as a color of royalty and elegance. In color psychology, ultramarine is often associated with feelings of calmness, serenity, and wisdom. It can evoke a sense of depth and introspection, making it suitable for designs that aim to inspire trust and credibility. Its unique depth makes it stand out from other blue shades.

The color #1D0197, a deep ultramarine, presents several accessibility considerations for web developers. Its low lightness value (approximately 11%) means that it requires very light text 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. When using #1D0197 as a background, text colors such as white (#FFFFFF) or very light grays are advisable. However, even with white text, careful attention should be paid to font size and weight to maximize readability, especially for users with visual impairments. Avoid using this color for crucial interactive elements without rigorous testing, as its darkness can make it challenging for some users to perceive subtle visual cues. Providing sufficient spacing and clear visual indicators is essential to enhance usability. Also, consider offering alternative color themes to accommodate users with different visual preferences and needs.
