#170BA8

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #170BA8, is a deep blue hue with a rich history. It is a color traditionally associated with royalty, wisdom, and spirituality. In art, genuine ultramarine pigment was originally derived from the precious gemstone lapis lazuli, making it incredibly expensive and highly prized by Renaissance painters. This association with luxury and rarity contributes to its enduring appeal. Today, synthetic ultramarine pigments are widely available, retaining the depth and vibrancy of the original without the exorbitant cost. The color is prominent in various fields, from art and design to fashion and branding.

The accessibility of #170BA8 (Ultramarine) should be carefully considered, particularly in text and user interface design. Due to its dark nature, using it as a background color necessitates light-colored text to ensure sufficient contrast, ideally meeting WCAG (Web Content Accessibility Guidelines) AA or AAA standards. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended. When used for interactive elements, ensure sufficient visual cues beyond color alone to cater to users with color vision deficiencies. For instance, adding underlines to links or icons alongside color changes can improve usability. Also, avoid using it as the sole indicator for crucial information, such as error messages, to prevent accessibility barriers for color-blind users. Careful color palette selection and incorporating other visual cues are essential for an inclusive design.
