#150E8D

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #150E8D, is a deep blue pigment historically made from ground lapis lazuli. The name comes from the Latin 'ultramarinus', meaning 'beyond the sea', as the pigment was imported into Europe from Asia. It is known for its intense, vibrant, and lasting color. In modern times, synthetic ultramarine is widely produced, offering the same color properties at a much lower cost. Ultramarine is used in various applications, including fine art, cosmetics, and textiles. The color's unique hue and depth make it a popular choice for creating a sense of sophistication and luxury.

The color #150E8D, Ultramarine, presents significant accessibility challenges due to its dark hue. When used as text, it requires a very light background to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratio. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Failure to meet these contrast levels makes content difficult to read for users with visual impairments. When used for UI elements, sufficient contrast is also crucial to ensure that users can easily distinguish interactive elements from the background. Consider using color contrast tools to verify compliance and adjust the color or background accordingly. To improve accessibility, pairing Ultramarine with a very light color like #FFFFFF or a pastel shade is advisable. Additionally, avoid using this color for critical information without proper contrast, and always provide alternative cues such as icons or text labels.
