General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #1B0F8B, is a deep blue pigment that has been highly valued since ancient times. Originally derived from the mineral lapis lazuli, Ultramarine was historically more precious than gold, making it a color reserved for royalty and religious figures. The name 'Ultramarine' literally means 'beyond the sea,' referring to its origin from distant lands. Today, synthetic Ultramarine is widely available, making it more accessible for various applications. This color is characterized by its strong, vibrant blue hue with a slight violet undertone. It is often associated with concepts such as depth, wisdom, and stability. In color psychology, blue is known to evoke feelings of calmness and trust.

The color #1B0F8B, also known as Ultramarine, presents some accessibility challenges, especially regarding text and background contrast. When using this dark shade of blue as a background, light-colored text (white, yellow, or light gray) is strongly recommended to ensure sufficient contrast for readability. A contrast ratio of at least 4.5:1 is crucial for compliance with WCAG AA standards, benefiting users with moderate visual impairments. For WCAG AAA compliance, a contrast ratio of 7:1 is required. It's important to test color combinations using accessibility tools to verify compliance. Avoid pairing Ultramarine with other dark colors, as this can render text illegible and create a poor user experience. Using Ultramarine as a text color should also be done cautiously, preferably on a very light background. Thoughtful consideration of color contrast is vital for inclusive design.
