General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #010F9A, is a deep, saturated blue hue reminiscent of the precious pigment derived from lapis lazuli. Historically, Ultramarine was highly valued for its brilliance and permanence, making it a favorite among Renaissance painters. Today, synthetic versions of the pigment offer a more affordable alternative, but the name continues to evoke a sense of luxury and artistic tradition. In color theory, Ultramarine sits between blue and violet on the color wheel, possessing a calming yet powerful presence. Its deep tone can create a sense of depth, mystery, or sophistication in design applications.

The hex color #010F9A, also known as Ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its very dark hue results in low contrast when used as text against a white or light-colored background. This can make it difficult for users with low vision to read the text. To ensure accessibility, it's crucial to use this color sparingly, especially for essential text or interactive elements. Always pair it with a very light color for sufficient contrast, adhering to WCAG guidelines (minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text). Consider providing alternative color schemes that offer better contrast for users with visual impairments. Tools like contrast checkers can help verify compliance. Avoid using this color alone to convey critical information; supplement it with clear labels or icons.
