General Information about Ultramarine (#170593)

The color #170593, also known as Ultramarine, is a deep shade of blue situated in the darker end of the color spectrum. Ultramarine is historically derived from the pigment lapis lazuli, a semi-precious stone. The name "ultramarine" literally means "beyond the sea," referring to the fact that the pigment was originally imported to Europe from Asia. In color theory, ultramarine is associated with depth, stability, and trust. It's often used to convey a sense of authority and sophistication. In digital contexts, it's essential to consider contrast ratios when using this color, especially for text, to ensure readability and accessibility, often pairing it with lighter shades to create balance.

The hex color #170593, a deep ultramarine, presents significant accessibility challenges, particularly in web design. Its very low lightness value means that text rendered in this color on a white background, or vice versa, will likely fail WCAG (Web Content Accessibility Guidelines) contrast ratio requirements. To ensure inclusivity, web developers should avoid using this color for text or interactive elements unless paired with a very light color that provides a sufficient contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Careful consideration of color combinations is crucial to meet the needs of users with visual impairments. Using tools like contrast checkers is highly recommended to validate the accessibility of color pairings with #170593.
