About Ultramarine (#0A118A)
The hexadecimal color #0A118A, commonly known as Ultramarine, is a deep, saturated shade of blue. It falls within the blue color family and is characterized by its high intensity and depth. In the RGB color model, #0A118A consists of 4% red, 7% green, and 54% blue. This composition explains its strong blue hue. Ultramarine has historical significance, originating from the pigment derived from the semi-precious stone lapis lazuli. The pigment was highly valued for its intense color and was often used in Renaissance paintings. Today, synthetic ultramarine is widely available and used in various applications, including paints, plastics, and cosmetics. The color is often associated with royalty, wisdom, and spirituality, making it a popular choice for branding and design projects aiming to convey these qualities.
The hex color #0A118A, also known as Ultramarine, presents significant accessibility challenges, particularly in web design. Due to its deep, saturated hue, it offers very low contrast when paired with lighter colors like white or yellow. This low contrast makes it difficult for users with visual impairments, such as those with low vision or color blindness, to read text or distinguish important elements on a webpage. To improve accessibility, it is crucial to use this color sparingly and to ensure a high contrast ratio with foreground elements. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text, as specified by the Web Content Accessibility Guidelines (WCAG). Consider pairing #0A118A with very light shades to achieve sufficient contrast, or use it primarily for decorative elements where readability is not critical. Always test color combinations with accessibility tools to verify compliance and ensure an inclusive user experience.
