#090791

General Information about Ultramarine

The color #090791, known as Ultramarine, is a deep, saturated blue hue. It is located in the blue region of the color spectrum and possesses a rich, almost royal quality. Ultramarine is derived from the pigment lapis lazuli, a semi-precious stone that was originally imported from Asia. This pigment was highly valued for its intense color and was historically used in paintings, particularly in Renaissance art, to depict the robes of the Virgin Mary. Nowadays, synthetic ultramarine pigments provide a more accessible and affordable alternative, but the name continues to evoke a sense of luxury and artistry. Ultramarine is often associated with depth, stability, and knowledge.

The color #090791, a deep ultramarine, presents significant accessibility challenges. Its low luminance of 1.56 cd/m² results in very poor contrast against standard white backgrounds, failing WCAG AA and AAA standards for normal and large text, as well as graphics and user interface components. Foreground text using this color should be avoided unless paired with a very light background to ensure readability. A lighter tint of the color or a contrasting color should be considered for essential UI elements and text. Tools like contrast checkers are crucial when using this color to ensure compliance with accessibility guidelines. Users with low vision might struggle to distinguish elements using this color from a dark background, highlighting the importance of sufficient contrast.
