It resides within the blue color spectrum and possesses a significant amount of blue pigment mixed with hints of red, giving it a slightly purplish undertone.

In the CMYK (Cyan, Magenta, Yellow, Key/Black) color model, it is composed of 81% cyan, 91% magenta, 0% yellow, and 36% black. Ultramarine's rich and intense hue makes it a popular choice in various applications, although care is needed due to accessibility concerns.

The color #1F0FA4, also known as Ultramarine, presents considerable accessibility challenges. Its dark hue and relatively low luminance result in poor contrast against lighter backgrounds, making it difficult for individuals with visual impairments to discern text or important visual elements. To improve accessibility, web developers should avoid using this color for text on white or light-colored backgrounds. Employing a lighter color for text or interactive elements against an Ultramarine background is strongly recommended to meet WCAG (Web Content Accessibility Guidelines) standards. Furthermore, relying solely on color to convey information should be avoided; supplementary cues like text labels or icons will ensure usability for all users, including those with color vision deficiencies. Testing with accessibility evaluation tools and considering user feedback are crucial steps in ensuring an inclusive user experience.
