#150E8A

General Information about Ultramarine (#150e8a)

The color #150e8a, commonly known as Ultramarine, is a deep and intense shade of blue, located towards the violet end of the spectrum. Historically, Ultramarine was derived from the precious gemstone lapis lazuli, making it one of the most expensive and highly prized pigments for centuries. Its name literally means 'beyond the sea,' reflecting its origin as a pigment imported to Europe from Asia. Today, synthetic Ultramarine is widely available, making it more accessible for various applications. This color evokes feelings of depth, tranquility, and sophistication, and it is often associated with royalty, wisdom, and spirituality. Its rich and saturated hue makes it a popular choice in art, design, and fashion, where it can add a touch of elegance and drama.

The hex color #150e8a, also known as Ultramarine, presents certain accessibility considerations for web development. Due to its deep, saturated blue hue, it is imperative to ensure sufficient contrast when used as either a background or text color. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using #150e8a for text on a white background, or vice versa, would likely fail these contrast tests. Therefore, it's crucial to pair it with lighter shades of yellow, white, or other high-contrast colors to ensure readability for users, especially those with visual impairments. Tools like contrast checkers can help determine if color combinations meet accessibility standards. Careful consideration of color choices ensures inclusivity and a better user experience for everyone.
