#070991

General Information about Ultramarine (#070991)

The hexadecimal color code #070991 represents a very dark shade of blue, often referred to as Ultramarine. In the RGB color model, it is composed of 2.75% red, 3.53% green, and 56.86% blue. This significant dominance of blue contributes to its deep and rich hue. The color is most closely associated with the deep blue pigment derived from the mineral lapis lazuli. Ultramarine is a cool color, evoking feelings of calmness, stability, and depth. It can be used to represent concepts like trust, intelligence, and authority. Due to its dark nature, it is important to consider contrast ratios when using it in design, particularly for text and interactive elements. The equivalent CMYK values are 95% cyan, 93% magenta, 0% yellow, and 43% black.

The color #070991, also known as Ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance value of approximately 3% means that text rendered in this color on a white background (or any light background) will have a very low contrast ratio. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal-sized text and 3:1 for large text to meet AA conformance. Ultramarine almost certainly fails these criteria, making it difficult for many users to read comfortably. To improve accessibility, it is essential to pair Ultramarine with a very light color such as white (#FFFFFF) or a light yellow (#FFFFE0). Avoid using it for essential text or interactive elements without ensuring sufficient contrast. Careful consideration should also be given to users with color vision deficiencies, as the deep blue hue may be difficult to distinguish from other dark colors for some individuals. Providing alternative color schemes or allowing users to customize the color palette can further enhance accessibility.
