About Ultramarine (#0E13A5)

Ultramarine, represented by the hexadecimal color code #0E13A5, is a deep, rich shade of blue. It closely resembles the pigment originally derived from lapis lazuli, a semi-precious stone, which historically made it one of the most expensive and highly prized blue pigments used by artists. The name 'ultramarine' literally means 'beyond the sea,' reflecting its origin as a pigment that came from overseas. In color theory, ultramarine is considered a cool color, evoking feelings of calmness, serenity, and intellect. It has a strong presence and can add depth and sophistication to designs. Its high saturation and relatively low lightness make it a color best used intentionally to avoid overwhelming visuals or creating accessibility issues.

The hex color #0e13a5, a deep ultramarine, presents significant accessibility challenges, especially in web design. Its very low luminance value of approximately 2.8% means that text rendered in this color requires very light foreground colors to meet WCAG (Web Content Accessibility Guidelines) standards for contrast. For instance, using white (#FFFFFF) as the text color provides a contrast ratio of about 7.5:1, which passes WCAG AA and AAA levels. However, slightly darker shades of gray or off-white might fall below the required contrast thresholds, making the text difficult for users with visual impairments to read. It's crucial to always test the color combination using accessibility tools to ensure compliance. When using #0e13a5 as a background, lighter elements and sufficient spacing are required to avoid visual fatigue. Alternative color combinations with high contrast should be considered for optimal user experience.
