About Ultramarine (#1109ab)

Ultramarine, represented by the hexadecimal color code #1109ab, is a deep, saturated shade of blue. It derives its name from the historical pigment made from ground lapis lazuli, a semi-precious stone. Ultramarine is characterized by its intense, almost violet undertones.

This color is often associated with royalty, wisdom, and spirituality. Its depth and richness make it a popular choice for branding, design, and artistic applications where a sense of sophistication and elegance is desired. However, due to its low brightness, it should be used carefully in contexts where readability is crucial.

The hex color #1109ab, also known as Ultramarine, presents some accessibility challenges, particularly for users with visual impairments. Its low lightness value (approximately 6%) means that text rendered in this color on a white or light background will have very poor contrast. According to WCAG guidelines, sufficient contrast is crucial for readability. To improve accessibility, it is strongly advised to pair #1109ab with significantly lighter colors, such as white or very light shades of yellow or green, for text or interactive elements. Alternatively, using #1109ab as a background color necessitates very light text colors to ensure readability. Avoid using this color for critical information or interactive elements without careful consideration of contrast ratios. Consider using online contrast checkers to verify compliance with accessibility standards and ensure a positive user experience for everyone, including individuals with visual impairments. Ensuring sufficient contrast will significantly improve the usability of your design.
