General Information about Ultramarine (#000798)

The color #000798, also known as Ultramarine, is a deep and intense shade of blue. It is located in the blue region of the color spectrum and is characterized by its high saturation and low brightness. Historically, ultramarine was derived from the mineral lapis lazuli, making it a highly prized and expensive pigment, often reserved for the most important figures in paintings, such as the Virgin Mary. Today, synthetic ultramarine is readily available, making it an accessible and widely used color. This color evokes feelings of calmness, trust, and authority, making it a popular choice for branding and design. In color psychology, deep blues are often associated with stability, confidence, and intelligence.

The color #000798, a deep ultramarine, presents several accessibility considerations for web developers. Due to its low lightness value, it offers very little contrast when paired with standard text colors like black or even dark grays. This can make content difficult to read, especially for users with visual impairments or color blindness. To ensure accessibility, it's crucial to use a light text color such as white or a very light gray (#FFFFFF or close) when using #000798 as a background. Employing tools that measure contrast ratios based on WCAG guidelines is highly recommended to verify compliance. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is generally advised. Additionally, avoid using this color as the sole means of conveying information, and always provide alternative cues such as text labels or icons.
