General Information about Ultramarine

Ultramarine, represented by the hexadecimal code #030F98, is a deep, rich blue color. It derives its name from the pigment originally made from lapis lazuli, a semi-precious stone. Historically, ultramarine was highly valued for its brilliance and permanence, often used in paintings and regarded as more precious than gold. In modern color theory, ultramarine is considered a cool color, associated with calmness, depth, and stability. Its unique spectral properties result in a color that appears both vibrant and serene. In digital applications, precise color calibration is important to accurately reproduce the intended shade of ultramarine.

The color #030F98, a deep ultramarine, presents considerable accessibility challenges. Its low luminance value (very dark) means that text rendered in this color on a white background, or vice versa, will likely fail WCAG (Web Content Accessibility Guidelines) contrast ratio requirements. This is crucial for users with visual impairments who rely on sufficient contrast to distinguish text from the background. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. To improve accessibility, consider using a lighter color for text on this background or pairing it with a very light accent color for graphical elements. It is also essential to avoid using this color as the sole indicator of interactive elements or important information, as colorblind users may not be able to differentiate it effectively. Adding labels or icons can significantly enhance usability for all users.
