This significant concentration of blue gives the color its characteristic deep blue appearance. In the CMYK color model, commonly used for printing, #051596 consists of 97% cyan, 86% magenta, 0% yellow, and 41% black. This indicates that it requires a substantial amount of cyan and magenta ink to reproduce accurately on printed materials. The color is often associated with sophistication, depth, and a sense of calm. Due to its dark nature, it is best used as an accent color or in combination with lighter hues to provide sufficient contrast and avoid overwhelming the viewer.

The hex color #051596, also known as Ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low lightness value (very dark) results in poor contrast against lighter backgrounds, making text or interactive elements difficult to perceive. According to WCAG guidelines, sufficient contrast ratios are crucial for readability and usability. To ensure accessibility, it is imperative to pair this color with very light hues (e.g., whites, light yellows, or light greens) that provide a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Furthermore, avoid using #051596 for essential visual information or controls without providing redundant cues, such as labels or icons, to accommodate users who may not be able to distinguish the color effectively. Thoroughly testing color combinations with accessibility tools is essential to identify and rectify any potential usability barriers.
