General Information

Ultramarine, represented by the hex code #1907AD, is a deep blue color reminiscent of the pigment derived from lapis lazuli. It is a shade that sits between blue and violet on the color spectrum, exuding a sense of depth and sophistication. Historically, ultramarine pigment was highly prized and expensive, making it a color associated with royalty and religious iconography. In modern color theory, ultramarine can be described using RGB (Red, Green, Blue) values of R:25, G:7, B:173. Its use in art, design, and fashion often aims to evoke feelings of tranquility, stability, and intellect. Due to its strong presence, it pairs well with contrasting colors like yellows and golds to create visually striking compositions. When used effectively, ultramarine can add a touch of elegance and formality to any project.

The hex color #1907ad, also known as Ultramarine, presents some accessibility challenges, particularly in text applications. Its dark hue means that careful consideration must be given to the foreground color to ensure sufficient contrast. 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 #1907ad as a background color, it's crucial to select a light text color such as white or a very pale yellow to meet these contrast requirements. Using darker text colors against this background can result in readability issues, especially for users with visual impairments. Additionally, relying solely on color to convey information is discouraged; developers should use supplementary cues like text labels or icons to ensure inclusivity for users with color vision deficiencies. Testing color combinations with accessibility tools is essential to validate compliance with accessibility standards and provide an inclusive experience for all users.
