General Information about Ultramarine

The color #10118B, commonly known as Ultramarine, is a deep and vivid shade of blue. It belongs to the blue color family and is characterized by its strong and intense hue. In the RGB color model, it is composed of 6.27% red, 6.67% green, and 54.51% blue. This particular combination results in a rich and saturated blue that is often associated with royalty, sophistication, and depth. Ultramarine has a long history, dating back to ancient times when it was derived from the mineral lapis lazuli. This made it a highly prized and expensive pigment, often reserved for use in religious art and other prestigious applications. Today, synthetic ultramarine is readily available, making it more accessible for various uses. The color is frequently used in graphic design, web design, and other visual media to evoke feelings of trust, stability, and authority. Its vibrant nature can also add a touch of drama and elegance to any project.

The color #10118B, also known as Ultramarine, presents some accessibility challenges, particularly regarding contrast. When used as a background color, it requires very light text to ensure readability. The dark nature of Ultramarine means that text colors like black or dark grays would be nearly invisible. White or very pale shades of yellow or green are better choices to achieve sufficient contrast. It's important to use contrast checking tools to verify that the contrast ratio meets WCAG (Web Content Accessibility Guidelines) standards, aiming for a minimum ratio of 4.5:1 for normal text and 3:1 for large text. Furthermore, avoid using this color for critical interactive elements without proper contrast, as users with visual impairments may struggle to identify and interact with them effectively. When used for decorative purposes, consider providing alternative visual cues or text labels to ensure all users can understand the information being conveyed. The intensity of Ultramarine can also be overwhelming for some users, so balancing its use with softer, more neutral colors can enhance the overall user experience and accessibility.
