Ultramarine

#040894

General Information about Ultramarine

Ultramarine, represented by the hex code #040894, is a deep and intense shade of blue. Historically, ultramarine pigment was derived from the precious mineral lapis lazuli, making it highly prized and expensive, often reserved for use in important religious artworks, particularly to depict the robes of the Virgin Mary. The name 'ultramarine' literally means 'beyond the sea,' reflecting the pigment's origin from minerals imported into Europe from distant lands. Modern ultramarine is typically produced synthetically, making it more accessible while retaining its rich color. Its spectral properties are dominated by short wavelengths, resulting in the characteristic blue hue. In color theory, ultramarine is considered a cool color, often associated with feelings of calmness, serenity, and wisdom.

The color #040894, a deep ultramarine, presents significant accessibility challenges, particularly in text applications. Its extremely low luminance contrast ratio against a white background is far below WCAG guidelines, making text virtually unreadable for users with visual impairments. To improve accessibility, consider using lighter text colors like white or yellow to provide sufficient contrast. Alternatively, lighten the background color or introduce a contrasting border around text elements. For decorative purposes, ensure that essential information isn't solely conveyed through this color. Providing text equivalents or alternative visual cues is crucial. Thoughtful design choices are necessary to make content inclusive and usable for all individuals, regardless of their visual abilities. Utilizing accessibility testing tools during development helps to identify and rectify potential contrast issues early on, ensuring a better user experience.
