General Information about Ultramarine

The color #170F8B, commonly known as Ultramarine, is a deep shade of blue that belongs to the broader blue color family. Ultramarine has a rich history, originally derived from the rare and expensive mineral lapis lazuli. Its name comes from the Latin 'ultramarinus', meaning 'beyond the sea', as the pigment was imported to Europe from mines in Asia. In the realm of color theory, Ultramarine is valued for its depth and intensity, often associated with qualities such as stability, wisdom, and confidence. Due to its depth and intensity, it can be used to add depth and interest to projects. It also pairs well with other colors, opening up creative possibilities for artists and designers alike.

The color #170F8B, also known as Ultramarine, presents some accessibility challenges, especially in web design. Due to its dark hue, it requires careful consideration of color contrast. When used as a background color, it's crucial to pair it with significantly lighter text colors to ensure readability. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to comply with WCAG (Web Content Accessibility Guidelines). Avoid using #170F8B for essential interactive elements or informational graphics without sufficient contrast, as users with visual impairments may struggle to perceive them. It is advisable to use color contrast checking tools during design to verify compliance and ensure an inclusive user experience. Consider providing alternative high-contrast themes or allowing users to customize colors to accommodate individual preferences and needs.
