General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #0D0398, is a deep and vibrant blue with a rich history. The term "ultramarine" originates from the Latin "ultramarinus," meaning "beyond the sea," as the pigment was originally imported from mines in Afghanistan by sea to Europe. Historically, it was derived from the precious gemstone lapis lazuli, making it one of the most expensive and highly prized pigments used by Renaissance artists. Today, synthetic ultramarine is widely available, offering the same brilliant hue at a more affordable price. In color theory, ultramarine is considered a cool color, evoking feelings of serenity, depth, and sophistication. It is often associated with qualities like trust, loyalty, and wisdom.

The color #0D0398, a deep Ultramarine, presents significant accessibility challenges, particularly concerning color contrast. When used as text, it requires a very light background to meet WCAG (Web Content Accessibility Guidelines) standards for readability. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended to ensure usability for individuals with visual impairments. If using this color for interactive elements like buttons or links, sufficient contrast is crucial. Consider pairing it with colors like #FFFFFF or #F0F0F0 to achieve adequate contrast. Avoid using it with dark or similarly saturated colors, as this will make the text difficult to read. Testing with accessibility tools is highly recommended to validate the color combinations. Also, remember to consider users with color vision deficiencies when selecting your color palette.
