#1908AB

General Information about Ultramarine

Ultramarine, represented by the hex code #1908AB, is a deep, vivid blue pigment that has been prized since antiquity. Originally derived from the semi-precious stone lapis lazuli, Ultramarine was highly valued for its intense color and rarity, making it more expensive than gold during the Middle Ages and Renaissance. This color is created by combining blue and violet. Synthetic Ultramarine was developed in the 19th century, making it more accessible. Today, Ultramarine is widely used in various applications, from fine art to industrial coatings, prized for its rich hue and lightfastness. In color psychology, blue is often associated with trust, stability, and intelligence, while violet can represent creativity and spirituality. As such, Ultramarine can evoke feelings of confidence and sophistication.

The hex color #1908AB, also known as Ultramarine, presents some accessibility challenges, particularly concerning color contrast. When used as text, it's crucial to pair it with a light background to ensure readability. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text according to WCAG guidelines. Using a color contrast checker is advisable to verify compliance. Conversely, when used as a background, pairing #1908AB with white or very light text can improve readability. Avoid pairing it with darker shades or colors with similar luminance, as this can strain the eyes and make content difficult to perceive for users with visual impairments. Also, consider providing alternative cues like icons or text labels for users who might have difficulty distinguishing colors.
