The hex color code #1A0992 corresponds to a deep shade of ultramarine blue. In the RGB color model, it is composed of 10.2% red, 3.53% green, and 57.25% blue. This composition places it firmly within the blue color spectrum, characterized by its high blue value and relatively low red and green values. Ultramarine blue is historically significant, originally derived from the rare and expensive mineral lapis lazuli. Its use was once reserved for royalty and the most prestigious artistic commissions.

It is often associated with depth, stability, and intelligence.

The hex color #1A0992, a deep ultramarine, presents accessibility challenges, particularly for users with visual impairments. Its low luminance value necessitates careful consideration of contrast ratios when used with text or other interactive elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text (14pt bold or 18pt regular) against its background. Therefore, using #1A0992 for text requires a very light background color to ensure readability. Using it for purely decorative purposes without conveying crucial information is acceptable. When used in charts or graphs, ensure sufficient color differentiation between #1A0992 and other colors used to represent data. Providing alternative text descriptions for visual elements is crucial for screen reader users. Additionally, avoid using #1A0992 as the sole indicator of important information, such as error messages, as colorblind users may not be able to distinguish it.
