General Information about Ultramarine

Ultramarine is a deep blue color that derives its name from the Latin "ultramarinus," meaning "beyond the sea," as it was originally imported from overseas. Historically, ultramarine was made from the semi-precious stone lapis lazuli, making it one of the most expensive and highly prized pigments. During the Middle Ages and Renaissance, it was reserved for use in paintings of religious figures, particularly the Virgin Mary, due to its rarity and expense. In modern times, synthetic ultramarine, also known as French ultramarine, is produced, making it more accessible and widely used. The color is known for its rich, intense hue and excellent lightfastness. It is a popular choice in art, design, and various other applications where a deep, vibrant blue is desired.

The hex color #080098, a deep shade of ultramarine, presents significant accessibility challenges. Its low luminance value means text rendered in white or very light colors is essential to achieve sufficient contrast. 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 #080098 as a background, careful consideration must be given to the text color and size to ensure readability for users with visual impairments. Tools like contrast checkers can help evaluate and adjust color combinations to meet accessibility standards. Avoiding its use for crucial interactive elements, such as buttons or links, is advisable unless accompanied by strong visual cues beyond color alone, such as labels or icons. Furthermore, it's important to test color combinations with assistive technologies to ensure compatibility.
