General Information about Ultramarine

The color #1F0398, known as Ultramarine, is a deep, vibrant shade of blue with a hint of violet. It belongs to the blue color family and is often associated with depth, stability, and wisdom. In the RGB (Red, Green, Blue) color model, #1F0398 is composed of 12.2% red, 1.2% green, and 59.6% blue. In the CMYK (Cyan, Magenta, Yellow, Key/Black) color model, it consists of 79% cyan, 98% magenta, 0% yellow, and 40% black. This color is frequently used in graphic design, web design, and branding to convey a sense of trust and authority. Ultramarine's historical significance stems from its use in fine art, particularly in paintings, where it was derived from the precious mineral lapis lazuli, making it an expensive and highly valued pigment. Today, synthetic versions of Ultramarine are readily available, making it more accessible for various applications.

The hex color #1F0398, also known as Ultramarine, presents considerable accessibility challenges, especially in web design. Due to its dark nature, text rendered in this color requires a very light foreground color to ensure sufficient contrast for readability. According to WCAG (Web Content Accessibility Guidelines) standards, the contrast ratio between the text and background should be at least 4.5:1 for normal text and 3:1 for large text. Using #1F0398 for text on a white background, for example, would fail these contrast tests, making it difficult for users, particularly those with visual impairments, to read the content comfortably. Therefore, when using this color, it is crucial to pair it with a very light color such as white (#FFFFFF) or a light shade of yellow or green to meet accessibility requirements. Alternative approaches include using #1F0398 sparingly as a background color with light-colored text or providing alternative color schemes that offer better contrast. Careful consideration of color contrast is vital to ensure an inclusive and accessible web experience for all users.
