General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #140E8A, is a deep, saturated shade of blue. It derives its name from the Latin 'ultramarinus', meaning 'beyond the sea', as the original pigment was imported from mines in Afghanistan by sea. Historically, ultramarine was a highly prized and expensive pigment, reserved for the most important artistic commissions, such as the robes of the Virgin Mary in Renaissance paintings. Chemically, the original ultramarine pigment was derived from the mineral lapis lazuli. Today, synthetic ultramarine is widely available, offering the same vibrant color at a fraction of the cost. It evokes feelings of calmness, serenity, and sophistication, making it a popular choice in various design applications.

The color #140E8A, a deep ultramarine, presents several accessibility considerations for web developers. Its dark hue necessitates light-colored text to ensure sufficient contrast for readability, adhering to WCAG guidelines for contrast ratios. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When used for interactive elements like buttons or links, providing clear visual cues beyond color alone is crucial, such as underlines, icons, or changes in size or shape on hover. Careful consideration should be given to users with visual impairments, including color blindness, by testing color combinations with tools that simulate different types of color vision deficiency. Avoid using this color as the sole indicator of important information. Thoughtful design choices are essential to create inclusive and accessible digital experiences.
