Ultramarine

#1B0098

General Information about #1B0098

The color #1B0098 is a deep shade of blue, specifically categorized as ultramarine. Ultramarine is historically significant as a pigment derived from lapis lazuli, a rare and expensive stone. This historical connection contributes to its association with royalty, luxury, and artistry. In the RGB color model, #1B0098 is composed of 10.6% red, 0% green, and 59.6% blue. In the CMYK color model, it consists of 82% cyan, 100% magenta, 0% yellow, and 40% black. This color is often associated with depth, stability, and confidence. Its intense nature makes it suitable for applications where a strong visual impact is desired, although care must be taken to ensure readability and accessibility when used in digital contexts. It should also be carefully used in designs.

The hex color #1B0098, a deep ultramarine, presents significant accessibility challenges, primarily due to its low luminance. When used as a foreground color, it requires very light text to ensure sufficient contrast for readability, especially for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text (14pt bold or 18pt regular) to meet WCAG AA standards. Insufficient contrast can make text difficult or impossible to read. When used as a background color, similarly light colors should be selected. Using tools like a color contrast checker is crucial to verify compliance and ensure inclusivity. Avoid pairing #1B0098 with dark or moderately dark colors, as this will certainly fail accessibility guidelines. Furthermore, consider providing alternative visual cues, such as icons or underlines, to convey information, as color alone should not be the sole method of communication.
