General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #120A91, is a deep, rich blue color reminiscent of the pigment derived from lapis lazuli. This color is often associated with depth, sophistication, and tranquility. In the RGB color model, it consists of 7.06% red, 3.92% green, and 56.86% blue. The CMYK color model representation is 87% cyan, 96% magenta, 0% yellow, and 43% black. Ultramarine is frequently used in graphic design, web development, and artistic applications to evoke feelings of calmness, reliability, and authority. Its dark tone makes it suitable for creating contrast and depth in visual compositions, but it is important to ensure sufficient contrast for accessibility when using it with text or interactive elements.

The color #120A91, a deep ultramarine, presents significant accessibility challenges. Its low luminance value results in a very low contrast ratio against a white background, making text and interactive elements difficult to read for users with visual impairments. According to WCAG guidelines, this color fails all contrast ratio success criteria for normal text (4.5:1) and large text (3:1). To improve accessibility, it is strongly recommended to use lighter text colors like white or very light grays on this background. Alternatively, consider using a lighter shade of blue or a completely different, more contrasting color palette to ensure readability for all users. Adequate color contrast is crucial for individuals with low vision, color blindness, or those using devices in bright sunlight. Providing sufficient contrast enhances the user experience and ensures inclusivity.
