General Information about Ultramarine

Ultramarine, represented by the hex code #2300A3, is a deep blue color with a slight violet undertone. It is derived from the natural pigment lapis lazuli, a semi-precious stone valued since ancient times. The name 'ultramarine' literally means 'beyond the sea,' reflecting its origin as a pigment that was imported to Europe from overseas. Historically, ultramarine pigment was extremely expensive, making it highly prized by artists. Today, synthetic ultramarine is widely available, offering the same vibrant color at a more affordable price. In color theory, ultramarine is considered a cool color, often associated with calmness, stability, and depth. It is frequently used in art, design, and branding to evoke feelings of trust and sophistication.

The hex color #2300a3, also known as Ultramarine, presents accessibility challenges due to its low luminance. When used as a text color, it requires careful consideration of the background color to ensure sufficient contrast for readability, especially for users with visual impairments. A light background is strongly recommended to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratio. Avoid pairing it with dark or similarly saturated colors, as this can result in a lack of differentiation and make content difficult to perceive. Using color contrast tools can help determine appropriate color pairings. Furthermore, avoid relying solely on color to convey important information; supplement color cues with text labels or other visual indicators to ensure accessibility for all users, including those with color vision deficiencies.
