General Information about Ultramarine

The hexadecimal color code #190B90 represents a deep, saturated shade of blue known as Ultramarine. In the RGB color model, it is composed of 9.8% red, 4.3% green, and 56.1% blue. This color is located in the blue-violet region of the color spectrum. Ultramarine has a rich history, initially derived from the precious stone lapis lazuli. Its name literally means "beyond the sea," as the pigment was imported to Europe from Asia by sea. Chemically, ultramarine is a complex sodium aluminosilicate with sulfur, giving it its distinct color. This color is often associated with feelings of calmness, trust, and stability. In art, it has been used extensively throughout history to depict royalty, religious figures, and scenes of grandeur. It is the colour of the Virgin Mary's cloak in many paintings. Today, synthetic ultramarine is widely available, making it more accessible than the original pigment.

The color #190B90, Ultramarine, presents accessibility challenges due to its dark hue. When used as a background, it necessitates very light text (white or near-white) to ensure sufficient contrast for readability, meeting WCAG standards for Level AA and ideally Level AAA. For individuals with low vision, ensuring a contrast ratio of at least 4.5:1 is crucial; for Level AAA, a contrast ratio of 7:1 is recommended. Avoid pairing this color with mid-tone or dark text, as it will likely fail accessibility checks. In user interface design, consider the cognitive load this color might impose, as strong blues can be overwhelming for some users. Providing options for users to adjust color schemes can improve the overall accessibility of the website or application. Also, avoid using this color to convey essential information without additional cues, such as text labels or icons, as colorblind users may not be able to distinguish it from other dark colors.
