#051693

General Information about Ultramarine

Ultramarine, represented by the hex code #051693, is a deep blue color with a rich history. The name "Ultramarine" originates from the Latin "ultramarinus," meaning "beyond the sea," as the pigment was originally imported from mines in Afghanistan. Historically, it was made from the semi-precious stone lapis lazuli. Because of the stone's rarity and the extensive process required to purify it, Ultramarine was a pigment of extraordinary price during the Middle Ages and Renaissance, usually reserved for the most important commissions, such as the robes of the Virgin Mary in paintings. Nowadays it is produced synthetically, so it is more accessible.

The color #051693, also known as Ultramarine, presents significant accessibility challenges, especially when used as text on a white or light-colored background. Its low luminance value results in very poor contrast, making it difficult for users with visual impairments to read. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Ultramarine is unlikely to meet these standards in many common use cases. To improve accessibility, consider using Ultramarine sparingly for decorative purposes only, or pairing it with very light colors to create a sufficient contrast ratio. Using a color contrast checker is highly recommended to ensure compliance with accessibility standards. Also avoid using this color for important user interface elements such as buttons or links, as it will be hard to see.
