In the RGB color model, #0d019a is composed of 5.1% red, 0.4% green, and 60.4% blue. This significant proportion of blue contributes to its intense and calming nature. The hex code #0d019a is widely used in web design and graphic design to represent this particular shade of blue.

Today, it is synthetically produced but retains its association with luxury and high quality.

The hex color #0d019a, a deep ultramarine, presents several accessibility considerations for web design. Due to its dark nature, it is crucial to ensure sufficient contrast when used as a background or text color. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. This color might not be suitable for smaller text sizes unless paired with a very light color like white or a pale yellow. When using #0d019a for interactive elements like buttons or links, providing clear visual cues for focus states is also essential. Consider adding a light-colored outline or a change in background color upon hover or focus to ensure that users with visual impairments can easily identify interactive elements. Additionally, avoid using this color as the sole indicator of important information, as users with color blindness may not be able to distinguish it effectively.
