Ultramarine
General Information
The hexadecimal color code #150D8A represents a dark shade of blue, often referred to as Ultramarine. In the RGB color model, it is composed of 8.24% red, 5.1% green, and 54.12% blue. This composition results in a color that is perceived as deep, rich, and somewhat mysterious. Ultramarine has a strong historical association with art, as it was originally derived from the gemstone lapis lazuli, making it one of the most expensive pigments. Its popularity in paintings throughout history speaks to its aesthetic appeal and enduring quality. In modern contexts, this color is frequently used in design and digital media to convey feelings of trust, stability, and sophistication. It is often chosen for branding in industries seeking to project an image of reliability and competence.
The color #150D8A, a deep ultramarine, presents several accessibility considerations for web development. Its low luminance value means it requires careful pairing with contrasting colors to ensure sufficient readability for users, especially those with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #150D8A as a background, light colors like white or bright yellow should be used for text. Conversely, if used as a text color, a light background is essential. The color's strong blue hue can also pose challenges for users with color vision deficiencies; therefore, relying solely on color to convey information should be avoided. Providing alternative cues, such as text labels or icons, is crucial to ensure inclusivity and a positive user experience. Proper use of ARIA attributes can further enhance accessibility by providing assistive technologies with semantic information about the color's role and meaning within the interface. Testing with accessibility evaluation tools is recommended.
