Ultramarine

#19118A

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #19118A, is a deep blue pigment historically derived from lapis lazuli. Its name originates from the Latin 'ultramarinus,' meaning 'beyond the sea,' as the pigment was imported to Europe from mines in Asia. Prized for its intense color and purity, ultramarine was extensively used by Renaissance painters, often reserved for depicting the robes of the Virgin Mary due to its high cost. Chemically, it is a complex sodium aluminum silicate with sulfur. Modern synthetic ultramarine, produced through a more affordable process, replicates the color's unique brilliance and stability. The color evokes feelings of serenity, depth, and sophistication, and is often associated with royalty and spirituality. In color psychology, blue hues are commonly linked to trustworthiness, intelligence, and calmness.

The color #19118a, also known as Ultramarine, presents significant accessibility challenges, especially when used as a foreground color on a white or light-colored background. Its low luminance value means text rendered in this color may not provide sufficient contrast for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Ultramarine might fail to meet these standards, potentially making content difficult to read for individuals with low vision or color blindness. To improve accessibility, consider pairing Ultramarine with a much lighter color, like a pale yellow or white, or using it sparingly for decorative elements rather than essential text. Tools that analyze color contrast can help determine if a given color combination meets accessibility requirements, ensuring that content is usable by a wider audience. Alternative color palettes should be explored to find hues that offer both aesthetic appeal and adequate contrast.
