General Information about Ultramarine (#0F138C)

The color #0F138C, commonly known as Ultramarine, is a deep, saturated blue hue that evokes feelings of depth, stability, and sophistication. It is part of the blue color family, which is often associated with calmness, trustworthiness, and intelligence. In the RGB color model, #0F138C is composed of 5.9% red, 7.5% green, and 54.9% blue. This significant amount of blue gives the color its distinctive and rich appearance. Ultramarine has a historical significance, as it was originally derived from the precious gemstone lapis lazuli, making it a highly valued pigment used in fine art and decoration. Its modern applications extend to various fields including web design, fashion, and interior design, where its powerful presence adds a touch of elegance and authority.

The color #0f138c, also known as Ultramarine, presents significant accessibility challenges due to its dark hue. When used as a background color, it necessitates very light text to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular). Ultramarine often fails to meet these standards with darker text options. For optimal accessibility, consider pairing #0f138c with colors like #ffffff (white) or very light shades of gray. Avoid using it with mid-tone or dark colors as text, as this can cause eye strain and make content inaccessible to users with visual impairments. Tools like contrast checkers can help verify compliance with accessibility standards.
