General Information about Ultramarine (#1A0D99)

The color #1A0D99, also known as Ultramarine, is a deep shade of blue that evokes feelings of serenity, depth, and sophistication. In the RGB color model, it consists of 10.2% red, 5.1% green, and 60% blue. This composition places it firmly within the blue color family. Ultramarine has a rich history, originally derived from the precious stone lapis lazuli. It was highly valued by Renaissance painters for its vibrant and lasting color. Today, synthetic ultramarine is widely available, making it accessible for various applications. The color is associated with qualities such as trust, loyalty, wisdom, confidence, intelligence, faith, truth, and heaven. In color psychology, blue is often used to promote a sense of calm and security. Its darkness gives a sense of regalness, and could be used for serious branding.

The color #1A0D99, a deep ultramarine, presents some accessibility challenges, particularly concerning color contrast. When used as a background color, it requires very light text (ideally white or near-white) to ensure sufficient contrast for readability. The Web Content Accessibility Guidelines (WCAG) recommend a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Due to its darkness, #1A0D99 will likely fail these contrast tests with many common text colors like black, gray, or even some shades of yellow or light blue. Therefore, careful consideration and testing are crucial when using this color in user interfaces or web design. Tools are available to check contrast ratios to ensure compliance with accessibility standards. Additionally, avoid using #1A0D99 as the sole method of conveying information, as users with color vision deficiencies may struggle to distinguish it from similar dark shades. Provide alternative cues, such as text labels or icons.
