About Ultramarine (#180395)

Ultramarine, represented by the hexadecimal color code #180395, is a deep, rich blue pigment that has been prized for centuries. Its name originates from the Latin 'ultramarinus,' meaning 'beyond the sea,' as it was originally imported from mines in Afghanistan via sea routes. Historically, ultramarine was derived from the mineral lapis lazuli, making it one of the most expensive pigments available, often reserved for the most important figures in religious art. In modern times, synthetic ultramarine is widely available, offering the same vibrant hue at a much lower cost. This color evokes feelings of royalty, depth, and intelligence, often associated with trust and stability. It is a versatile color that can be used in various applications, from art and design to fashion and branding.

The color #180395, also known as Ultramarine, presents significant accessibility challenges, particularly in text-based applications. Due to its dark nature, it requires very light foreground colors to ensure sufficient contrast for readability, ideally white (#FFFFFF) or near-white hues. Using colors with insufficient contrast can lead to difficulties for users with visual impairments, including those with low vision or color blindness. Accessibility standards, such as WCAG, require a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Therefore, careful consideration is needed when using Ultramarine to ensure compliance with accessibility guidelines. Implementing contrast checking tools during the design process is highly recommended. Furthermore, avoid using Ultramarine as the sole means of conveying information, and consider alternative indicators like icons or text labels.
