Ultramarine

#190DA7

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #190DA7, is a deep, intense shade of blue that has historically been derived from the mineral lapis lazuli. This pigment has been prized for centuries, particularly in fine art, where it was used by Renaissance painters to depict the robes of the Virgin Mary and other important figures. The name 'ultramarine' literally means 'beyond the sea,' reflecting its origin as a pigment imported to Europe from distant lands. Modern ultramarine is typically produced synthetically, offering a more affordable and consistent alternative to the natural pigment. Its unique hue lends itself to a variety of applications, from fine art to graphic design.

The color #190DA7, a deep ultramarine, presents some accessibility challenges. Its dark hue results in a low contrast ratio against white text, potentially making it difficult for users with visual impairments to read. To improve accessibility, consider using a lighter text color such as white or yellow to ensure sufficient contrast, ideally aiming for a contrast ratio of at least 4.5:1 as recommended by WCAG guidelines. Additionally, avoid using this color as the sole means of conveying important information; supplement it with text labels or other visual cues to ensure usability for all users. When used as a background, pair it with high-contrast elements. For interactive elements like buttons, ensure sufficient size and spacing to improve usability for users with motor impairments.
