Ultramarine

#140395

General Information

Ultramarine, represented by the hexadecimal color code #140395, is a deep and rich shade of blue. Historically, ultramarine was derived from the rare and expensive mineral lapis lazuli, making it a highly prized pigment, particularly in Renaissance art. Today, synthetic ultramarine is readily available, offering the same vibrant hue without the exorbitant cost. It is characterized by its strong saturation and slight reddish undertone, which sets it apart from other blues. In color theory, ultramarine is considered a cool color, evoking feelings of calmness, sophistication, and depth. Its unique chromatic properties make it versatile for both digital and physical applications.

The color #140395, a deep ultramarine, presents significant accessibility challenges. Its low luminance contrast against both white and light backgrounds makes text illegible for users with visual impairments, including those with low vision or color blindness. To ensure inclusivity, it's crucial to use this color sparingly, primarily for decorative elements rather than essential information. When used for text or interactive elements, it must be paired with a very light color (e.g., #FFFFFF) to achieve a contrast ratio that meets WCAG guidelines (minimum 4.5:1 for normal text and 3:1 for large text). Careful consideration is needed to avoid excluding users who rely on sufficient contrast for readability and navigation. Employing contrast checking tools is essential to validate the accessibility of color combinations.
