General Information about Ultramarine

It is characterized by its high intensity and depth, reminiscent of the historical pigment derived from lapis lazuli. In the RGB color model, #11098F is composed of 6.7% red, 3.5% green, and 56.1% blue. This composition gives it a strong blue dominance. In the CMYK color model, it consists of approximately 88% cyan, 94% magenta, 0% yellow, and 44% black. This color is often associated with feelings of sophistication, depth, and mystery. Due to its saturation and hue, it can evoke a sense of tranquility and intellectual curiosity. The color has historical significance to lapis lazuli and symbolizes wisdom. As a dark shade, it's very effective when used to highlight different parts of design but is not very effective with web design.

The color #11098F, a deep ultramarine, presents significant accessibility challenges, especially in text applications. Its low luminance value of approximately 1% means it offers very little contrast against darker backgrounds, making it nearly invisible. When used with white text, the contrast ratio is also low (around 1.9:1), falling far short of the WCAG's minimum requirement of 4.5:1 for normal text and 3:1 for large text. This color is therefore unsuitable for body text or any element requiring readability. To enhance accessibility, consider using lighter shades of blue or pairing it with much lighter colors, such as yellows or off-whites, to achieve an adequate contrast ratio. Tools like contrast checkers can help determine appropriate color combinations for optimal readability and compliance with accessibility standards. Avoid using this color for important UI elements where user interaction is key without considering the contrast and its effects on visually impaired users.
