General Information about #1C0593 (Ultramarine)

Ultramarine pigments were originally derived from the precious stone lapis lazuli, making it one of the most expensive and highly prized pigments for centuries. Its use can be traced back to medieval paintings, where it was reserved for the most important figures and elements. Today, synthetic ultramarine is widely available, retaining the color's rich and intense hue. This color family often conveys feelings of trust, loyalty, wisdom, confidence, intelligence, faith, truth, and heaven. It is often associated with stability and is a popular choice for corporate branding for these reasons.

The color #1C0593, a deep ultramarine, presents significant accessibility challenges. Its very low luminance (brightness) means that text rendered in this color against a white background, or vice versa, will likely fail WCAG (Web Content Accessibility Guidelines) contrast ratios for both normal and large text. This is especially true for users with visual impairments, who may struggle to distinguish the text from the background. To improve accessibility, consider using a much lighter color for text on a #1C0593 background, or a much darker color for the background if #1C0593 is used for text. Another possibility would be using this color for decorative elements rather than crucial textual information. Tools are available to check color contrast ratios to ensure compliance with accessibility standards and a better user experience.
