Ultramarine

#090296

General Information

Ultramarine, represented by the hexadecimal color code #090296, is a deep blue pigment originally derived from the precious gemstone lapis lazuli. Its name literally means 'beyond the sea,' reflecting its historical origin from stones imported into Europe from Asia. Chemically, modern ultramarine is a complex sodium aluminosilicate containing sulfur, giving it its characteristic color. This pigment is highly valued for its intense and vibrant hue, excellent lightfastness, and relative resistance to fading. It has been used for centuries in paintings, decorative arts, and even cosmetics. Synthetic ultramarine, also known as French ultramarine, provides a more affordable and widely available alternative to the natural pigment.

The color #090296, a deep ultramarine, presents several accessibility considerations for web development. Due to its low luminance, it requires careful pairing with contrasting colors to ensure readability for users, especially those with visual impairments. Using it as a background color necessitates light-colored text for sufficient contrast, ideally adhering to WCAG (Web Content Accessibility Guidelines) AA or AAA standards. Tools like contrast checkers can assist in verifying compliance. Furthermore, avoid using this color as the sole indicator for interactive elements like links or buttons, as users might miss them. Supplement it with clear labels, icons, or other visual cues to enhance usability for everyone, including individuals with color vision deficiencies. Proper attention to contrast and redundant coding practices will make content accessible for people of all abilities.
