#100B84

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #100B84, is a deep, rich shade of blue-violet. It belongs to the blue color family and is often associated with qualities like depth, stability, and sophistication. This color is created by combining a small amount of red and green with a large amount of blue, resulting in its characteristic hue. Ultramarine has a relatively low saturation and brightness, which contributes to its darker appearance. It is commonly used in graphic design, web development, and interior decoration to evoke feelings of calmness, trust, and elegance. In printing, the color needs to be created using the CMYK color space because printing devices can't reproduce hex colors directly. The color appears different on every display because it depends on the calibration and quality.

The hex color #100b84, also known as Ultramarine, presents some accessibility challenges, particularly for text-based content. Its dark hue results in a low contrast ratio when paired with similarly dark colors, making it difficult for users, especially those with visual impairments, to read the text. To improve accessibility, it is recommended to use #100b84 with light colors such as white (#ffffff) or very light grays. Using online contrast checkers is a good approach to determine compliance with accessibility standards like WCAG. When using this color as a background, ensure that the foreground text has sufficient contrast. Consider providing alternative color schemes or themes that offer better contrast options for users with different visual needs. Additionally, avoid using #100b84 as the sole means of conveying important information, as colorblind users may not be able to perceive it.
