General Information about #010497

The color #010497, also known as Ultramarine, is a deep and intense shade of blue. It is located in the blue region of the color spectrum, exhibiting a strong saturation and relatively low brightness. This hex code represents a very dark variant of blue, leaning towards indigo. Historically, ultramarine pigment was derived from the mineral lapis lazuli, making it a highly valued and expensive color used in fine art. Today, synthetic ultramarine is widely available. In color psychology, deep blues like this are associated with stability, trust, and authority. It often conveys a sense of calmness and reliability, although its darkness can also evoke feelings of melancholy or seriousness. Its deepness can be useful to define the layout structure in website design and call attention to the most important navigation items.

The hex color #010497, also known as Ultramarine, presents significant accessibility challenges, especially in text applications. Due to its very dark nature, it requires extremely light text (ideally white or near-white) to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using #010497 as a background color with dark text would fail these criteria, making it difficult for users, particularly those with visual impairments, to read the content. Designers should carefully consider color contrast when using this hue in user interfaces, opting for lighter foreground colors or adjusting the background shade for better accessibility. Testing with accessibility tools is highly recommended.
