Ultramarine

#070299

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #070299, is a deep, saturated blue hue reminiscent of the pigment derived from lapis lazuli. Historically, ultramarine was highly prized for its brilliance and permanence, making it a favored color among artists for centuries, particularly during the Renaissance. The name 'ultramarine' literally means 'beyond the sea,' referring to the fact that the pigment was originally imported to Europe from mines in Afghanistan. Today, synthetic ultramarine is readily available, offering the same vibrant color at a fraction of the cost. This intense blue possesses a strong visual impact and evokes feelings of depth, mystery, and sophistication.

The color #070299, a deep ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its very low luminance (brightness) results in extremely poor contrast against common background colors like white. Text rendered in this color on a white background, or conversely, white text on this color, will be difficult, if not impossible, for many users to read comfortably. Following WCAG guidelines, the contrast ratio must be at least 4.5:1 for normal text and 3:1 for large text. Ultramarine is unlikely to meet these standards with lighter backgrounds. Web developers should use contrast checking tools to verify sufficient contrast and consider alternatives with higher luminance or pair ultramarine with carefully chosen, contrasting colors to ensure readability and usability for all users, including those with low vision or color blindness. Avoid using it for critical information.
