Ultramarine

#1D0395

General Information about Ultramarine

The hex color #1D0395, commonly known as Ultramarine, is a deep, rich shade of blue with a hint of violet. It belongs to the blue color family and is often associated with depth, sophistication, and royalty. In the RGB color model, it is composed of 11.4% red, 1.2% green, and 58.4% blue. The name 'Ultramarine' originates from the Latin 'ultramarinus,' meaning 'beyond the sea,' as the pigment was originally derived from lapis lazuli imported from distant lands. Historically, it was a highly prized pigment, often more expensive than gold, and reserved for use in important paintings, particularly for depicting the robes of the Virgin Mary. Today, synthetic versions allow for broader and more accessible use of this striking color.

The hex color #1D0395, also known as Ultramarine, presents significant accessibility challenges, especially in web design. Its dark nature results in very low contrast when paired with standard text colors like black or dark gray. Using this color as a background requires extremely light text (white or very pale shades) to meet WCAG (Web Content Accessibility Guidelines) standards for readability. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is essential. When using Ultramarine, careful consideration must be given to color combinations to ensure that users with visual impairments can perceive the content effectively. Tools for checking color contrast ratios should be utilized during the design process. Avoiding its use for critical interactive elements is also advisable unless accompanied by clear visual cues beyond color alone.
