#08128A

General Information about Ultramarine

The color #08128A, commonly known as Ultramarine, is a deep and vivid shade of blue. It belongs to the blue color family and is characterized by its rich and intense hue. Ultramarine derives its name from the Latin word 'ultramarinus,' meaning 'beyond the sea,' as it was originally imported from overseas, primarily from sources in Afghanistan where the mineral lapis lazuli, the source of natural ultramarine pigment, was mined. The pigment was highly valued in the past and was used for paintings and illuminations. Today, synthetic ultramarine is readily available, offering the same vibrant color at a lower cost. It is widely used in various applications such as art, cosmetics, and textiles.

The color #08128A, a deep ultramarine, presents several accessibility considerations. Its low luminance value means it requires careful pairing with text and other interactive elements. Insufficient contrast against a white background, for instance, would make content difficult to read for users with low vision. 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 #08128A as a background, ensure that text is a light color, such as white or a pale yellow, to meet these contrast requirements. Additionally, avoid using this color as the sole indicator of interactive elements, such as links or buttons. Supplement color with other visual cues like underlines, icons, or text labels to ensure accessibility for users who are colorblind.
