About Ultramarine

Ultramarine is a deep blue color, originally derived from the pigment made by grinding lapis lazuli stone. The name comes from the Latin "ultramarinus", literally meaning "beyond the sea", as the pigment was imported into Europe from Asia. It is a rich, vibrant, and intense color that has been highly valued throughout history, particularly in art. Nowadays, synthetic ultramarine is widely available, offering the same beautiful hue at a more accessible price. This color is often associated with royalty, wisdom, and spirituality due to its historical significance and striking appearance.

The color #0F168C, also known as Ultramarine, presents some accessibility challenges, particularly in web design. Due to its deep, saturated hue and low luminance, it may not provide sufficient contrast when used as text against a white or light-colored background. This can make it difficult for users with visual impairments, such as those with low vision or color blindness, to read the text effectively. To ensure accessibility, it's crucial to pair this color with lighter shades to meet WCAG (Web Content Accessibility Guidelines) contrast ratio requirements. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Tools like contrast checkers can help verify compliance. Additionally, avoid using this color as the sole means of conveying information, as users with color blindness may not be able to distinguish it.
