#0D0BA9

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #0D0BA9, is a deep blue hue with a rich history and cultural significance. The name 'Ultramarine' originates from the Latin 'ultramarinus,' meaning 'beyond the sea,' as the pigment was initially imported from mines in Afghanistan by sea to Europe during the Middle Ages. Historically, it was derived from the semi-precious stone lapis lazuli, making it one of the most expensive and prized pigments. Today, synthetic versions provide more affordable and accessible alternatives. Ultramarine's association with royalty and spirituality is reflected in numerous artworks throughout history, adding an air of elegance and prestige. Its deep, captivating tone makes it a versatile color choice across different fields.

The hex color #0D0BA9, also known as Ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its dark nature results in a low contrast ratio against typical light backgrounds, making text and interface elements difficult to discern. According to WCAG guidelines, this color fails to meet the minimum contrast requirements for normal text (4.5:1) and large text (3:1). To improve accessibility, it is crucial to pair Ultramarine with very light colors, such as white or pale yellow, to ensure sufficient contrast. Alternatively, consider using Ultramarine sparingly for decorative elements rather than essential information. Employing contrast checker tools during the design process can help identify and address potential accessibility issues early on, creating a more inclusive user experience.
