General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #0f07ad, is a deep blue hue that has been prized for centuries. Historically, ultramarine pigment was derived from the precious gemstone lapis lazuli, making it one of the most expensive and sought-after pigments during the Renaissance. The name "ultramarine" literally means "beyond the sea," referring to the pigment's origin from stones imported into Europe from distant lands. In color theory, ultramarine is considered a primary color, forming the foundation for countless other shades when mixed with other colors. It exudes a sense of depth, sophistication, and tranquility, making it a popular choice across various creative fields. Modern ultramarine is synthetically produced, making it more accessible while retaining its captivating hue.

The hex color #0f07ad (Ultramarine) presents significant accessibility challenges, particularly concerning contrast. Its low luminance value of approximately 1% means that text or other elements rendered in this color against a white or light-colored background will likely fail WCAG (Web Content Accessibility Guidelines) contrast ratio requirements. A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text. Therefore, using #0f07ad for text requires careful consideration of the background color; lighter text colors such as white, #ffffff, or very light shades of gray, #cccccc, are recommended to ensure readability. When used as a background color, foreground elements should be light. Moreover, consider providing alternative color schemes for users with visual impairments to ensure inclusivity.
