General Information about Ultramarine

Ultramarine, represented by the hex code #150098, is a deep blue color with a rich history. The name "ultramarine" originates from the Latin "ultramarinus," meaning "beyond the sea," as the pigment was originally imported from mines in Afghanistan by sea. This color was highly prized during the Middle Ages and Renaissance, used primarily by painters for depicting the robes of the Virgin Mary. Natural ultramarine was made from the gemstone lapis lazuli, making it one of the most expensive pigments available. Today, synthetic ultramarine is widely available, offering the same vibrant hue at a more affordable cost. It's known for its exceptional lightfastness and stability.

The color #150098, a deep ultramarine, presents accessibility challenges, particularly regarding color contrast. When used for text, it's crucial to pair it with a light color for the background to ensure readability. A contrast ratio of at least 4.5:1 is recommended for small text and 3:1 for large text to meet WCAG (Web Content Accessibility Guidelines) AA standards. Using online contrast checkers can help verify compliance. Avoid using this color for essential information or interactive elements without careful consideration of its contrast against the surrounding colors. When paired with a dark background, it can cause eye strain. Consider using a lighter tint of ultramarine or another contrasting color for improved accessibility for users with visual impairments or color blindness.
