About Ultramarine (#0D0593)

The hex color code #0D0593, also known as Ultramarine, represents a dark shade of blue in the RGB color model. It is composed of 5.1% red, 2% green, and 57.6% blue. This color is often associated with qualities such as depth, stability, and trust. In color psychology, blue is known to evoke feelings of calmness, serenity, and security. Ultramarine, being a darker shade, tends to convey a sense of seriousness and authority. In the context of web design and graphic arts, #0D0593 can be effectively used to create a professional and trustworthy brand image. Its rich pigmentation allows it to stand out as a focal point, or serve as a sophisticated background that enhances other colors and design elements on the page.

The color #0D0593, a deep ultramarine, presents several accessibility considerations for web development. Its low luminance value means it requires careful pairing with text and other interactive elements. According to WCAG guidelines, sufficient contrast is essential for readability and usability, especially for users with visual impairments. When using #0D0593 as a background, ensure that any foreground text meets at least a 4.5:1 contrast ratio for normal text and 3:1 for large text. Tools like contrast checkers can help verify compliance. Avoid using this color for elements that need to convey critical information on their own, such as error messages or alerts, unless accompanied by clear icons and labels. Considering colorblind users is also important. As a dark blue, #0D0593 might be difficult for individuals with tritanopia (blue-yellow color blindness) to distinguish from black or other dark shades. Providing alternative cues, such as text or symbols, can help address this. Proper use of ARIA attributes and semantic HTML can further enhance accessibility for assistive technologies.
