General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #041290, is a deep, rich blue color that evokes feelings of tranquility, depth, and sophistication. It derives its name from the Latin 'ultramarinus,' meaning 'beyond the sea,' as it was originally made from lapis lazuli imported from Asia. This pigment was highly prized in Renaissance painting for its vibrant hue and durability. Modern ultramarine is a synthetic pigment, chemically identical to natural ultramarine but produced on a larger scale and at a lower cost. In color psychology, blue is often associated with trust, stability, and intelligence, making ultramarine a suitable choice for brands and designs that wish to convey these qualities. The color has a wavelength between 450 and 495 nanometers, it is considered a cool color that can create a calming and soothing atmosphere.

The color #041290, a deep ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance value results in very poor contrast against light backgrounds, making text and other interface elements difficult to discern. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. This dark blue is unlikely to meet these standards when paired with common background colors like white or light gray. To improve accessibility, consider using a much lighter color for text or interactive elements displayed on an ultramarine background, or vice versa. Alternatives include using this color sparingly for purely decorative purposes, or pairing it with high-contrast hues like yellow or white in larger graphical elements where readability is not paramount. Always test color combinations with accessibility tools to ensure compliance with WCAG standards and to provide a usable experience for all users.
