#0F1289

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #0F1289, is a deep, rich blue hue. Historically, ultramarine was derived from the precious gemstone lapis lazuli, making it one of the most expensive and highly prized pigments. This association has imbued the color with connotations of luxury, sophistication, and importance. In color psychology, ultramarine is often linked to feelings of trust, loyalty, and wisdom. It's a color that evokes a sense of calm and stability, while also suggesting depth and mystery. Due to its historical significance and psychological impact, ultramarine is a powerful color choice for designs that aim to convey authority, elegance, or a sense of timelessness. In modern applications, synthetic ultramarine is commonly used, which makes it more accessible.

The color #0F1289, a deep ultramarine, presents significant accessibility challenges, particularly concerning color contrast. When used as text against a white background, or vice versa, it fails to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratio. This can make content difficult to read for users with visual impairments, including those with low vision or color blindness. To improve accessibility, consider pairing #0F1289 with very light shades of yellow, orange, or green for text, or using it sparingly for decorative elements. Alternatively, ensure a sufficient contrast ratio by using a much lighter color as background, but ensure that the chosen text color is carefully evaluated for accessibility. Tools such as contrast checkers can help verify compliance with accessibility standards, ensuring that your designs are inclusive and usable by everyone.
