Ultramarine

#1B05AE

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #1B05AE, is a deep, rich blue pigment that has been highly valued throughout history. Derived from the Latin 'ultramarinus,' meaning 'beyond the sea,' it was originally made from the semi-precious stone lapis lazuli, imported from Afghanistan. This precious origin made it more expensive than gold during the Middle Ages and Renaissance, often reserved for painting the robes of the Virgin Mary. Today, synthetic ultramarine is readily available, offering the same vibrant hue at a fraction of the cost. The color is known for its intense depth and purity, making it a favorite among artists and designers alike. It falls under the blue color family and exhibits a strong presence and timeless appeal.

The color #1B05AE, also known as Ultramarine, presents some accessibility challenges. Its dark hue results in a low contrast ratio against white text, which can make it difficult for users with visual impairments to read. To improve accessibility, consider using a lighter text color such as white or a pale yellow, which would significantly increase the contrast ratio. Additionally, avoid using #1B05AE for critical user interface elements where readability is paramount. When using this color as a background, ensure that all interactive elements have sufficient contrast and are easily distinguishable. Moreover, providing alternative styling options for users with specific visual needs can further enhance the overall accessibility of your design. Remember to test your color choices with accessibility tools to ensure compliance with WCAG guidelines.
