General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #0D138E, is a deep and rich shade of blue. Historically, ultramarine pigment was derived from the gemstone lapis lazuli, making it a highly prized and expensive color. This association with rarity and luxury contributes to its perception as a sophisticated and elegant color. In color psychology, blue is often linked to feelings of calmness, stability, and trust. Ultramarine, with its depth and intensity, can evoke a sense of authority and wisdom.

Its unique properties make it a standout choice for many design projects.

The hex color #0D138E, also known as Ultramarine, presents significant accessibility challenges due to its dark hue. When used as a foreground color for text, it requires a very light background to ensure sufficient contrast for readability, particularly for individuals with visual impairments. According to WCAG guidelines, the contrast ratio between the text and background should be at least 4.5:1 for normal text and 3:1 for large text. Using #0D138E on a dark or moderately colored background would likely fail these accessibility standards, making the text difficult or impossible to read for many users. Therefore, careful consideration must be given to background color selection when employing #0D138E to maintain web accessibility and inclusivity. Light shades of white, yellow or gray are suitable backgrounds.
