General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #010297, is a deep, saturated blue hue. Historically, ultramarine pigment was derived from lapis lazuli, a rare and precious stone, making it one of the most expensive and highly prized pigments used by Renaissance artists. Its name literally means 'beyond the sea,' referring to its origin from stones imported into Europe from Asia. In modern color theory, #010297 falls into the blue color family, known for its associations with calmness, stability, and authority. This particular shade of ultramarine is especially potent and commands attention, often used to convey a sense of seriousness and sophistication, setting it apart from lighter and more pastel shades of blue.

The color #010297, a deep ultramarine, presents several accessibility considerations for web development. Due to its low lightness value, it is crucial to ensure sufficient contrast against text or other foreground elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #010297 as a background, lighter colors like whites, yellows, or very light blues should be employed for text to meet these standards. Additionally, avoid using this color for crucial visual elements without providing alternative cues, as users with visual impairments may struggle to perceive them. Consider providing labels or icons alongside color-coded information to enhance accessibility for all users, including those with color vision deficiencies. Careful attention to color contrast and redundancy in visual cues are key to creating inclusive designs with this deep color.
