Ultramarine

#030495

General Information about Ultramarine

The color #030495, also known as Ultramarine, is a deep, rich blue hue that sits firmly within the blue color family. It is characterized by its strong saturation and relatively low brightness. The name "Ultramarine" originates from the Latin "ultramarinus," meaning "beyond the sea," as the pigment was originally derived from lapis lazuli, a gemstone sourced from distant lands, primarily Afghanistan. Historically, ultramarine was one of the most expensive and prized pigments, often reserved for use in religious paintings and other high-value artwork. Nowadays the colour is created synthetically. The chemical composition gives a great richness to the colour and is thus used in design, art and many other forms of expressions.

The color #030495, a deep ultramarine, presents significant accessibility challenges, especially for users with visual impairments. Its low luminance value of approximately 2% means text or interactive elements rendered in this color require extremely high contrast against the background to be legible. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using #030495 as a primary text color is strongly discouraged unless paired with a very light background, such as white or a very pale yellow. Even then, careful testing with users is essential to ensure readability. As a background color, #030495 can work better, but foreground elements must still be carefully chosen for sufficient contrast. For enhanced accessibility, consider using a lighter shade of blue or implementing a contrast checker tool during the design process to validate color choices.
