General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #031398, is a deep and intense shade of blue. It is named after the pigment derived from lapis lazuli, a semi-precious stone that was historically ground into a powder and used as a vibrant blue pigment, especially during the Renaissance. The term 'ultra' means 'beyond' and 'mare' means 'sea' in latin. The high cost and rarity of lapis lazuli made ultramarine pigment highly valued, often reserved for the most important figures in paintings, such as the Virgin Mary. Today, synthetic ultramarine is widely available, offering the same brilliant hue at a fraction of the cost. This color evokes feelings of depth, stability, and sophistication, often associated with trust and authority. It is used across various industries, from art and design to marketing and branding, to convey these qualities.

The color #031398, a deep ultramarine, presents significant accessibility challenges, particularly in text applications. Due to its low luminance, achieving sufficient contrast against lighter backgrounds is crucial. 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 #031398 for text, ensure that the background color is significantly lighter to meet these contrast requirements. Tools like WebAIM's Contrast Checker can assist in verifying compliance. Additionally, avoid using this color as the sole indicator of interactive elements, as users with color vision deficiencies may not be able to distinguish them. Providing alternative visual cues, such as underlines or icons, is essential for inclusive design. Considering the dark nature of this color, it is more suited for decorative elements or as a background color with light-colored text overlaid.
