Ultramarine

#10178B

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #10178B, is a deep, vibrant blue hue. It derives its name from the Latin 'ultramarinus,' meaning 'beyond the sea,' as it was originally imported from overseas, particularly from Afghanistan, where the precious mineral lapis lazuli was mined. This mineral was ground to create the pigment, making Ultramarine one of the most expensive and highly prized colors during the Middle Ages and Renaissance. Historically, it was favored by artists for painting the robes of the Virgin Mary and other important figures, symbolizing holiness and royalty. Its chemical composition primarily consists of a complex sodium aluminum silicate with sulfur, giving it its distinctive color.

The color #10178B, Ultramarine, presents some accessibility challenges. Its dark hue results in a low contrast ratio against light backgrounds like white. This can make text difficult to read for users with visual impairments. To improve accessibility, it's recommended to use Ultramarine with very light text colors such as white (#FFFFFF) or very bright yellows. Additionally, using larger font sizes or adding a text shadow can enhance readability. In design, consider using this color sparingly for decorative elements rather than essential information. When using Ultramarine as a background, ensure that all interactive elements have clear visual cues and sufficient contrast to be easily identifiable. Providing alternative color schemes for users who require them can also improve accessibility and inclusivity.
