Ultramarine
General Information about Ultramarine
The hex color #180598, also known as Ultramarine, is a deep shade of blue located in the blue-violet hue range of the color spectrum. It is created by combining a small amount of red and green, creating a strong dark blue. Ultramarine is known for its rich and intense hue, evocative of the pigment derived from lapis lazuli. Historically, ultramarine pigment was highly valued and costly, making it a prized color in art. In modern times, synthetic ultramarine is readily available, offering the same striking hue at a fraction of the cost. In web development and design, ultramarine can be used to create a sense of depth and sophistication, although careful consideration should be given to its accessibility due to its low luminance value, especially when used for text or interactive elements.
The color #180598, a deep ultramarine, presents significant accessibility challenges. Its low luminance value results in poor contrast against light backgrounds, making text and interactive elements difficult to read for users with visual impairments. According to WCAG guidelines, it fails most contrast ratio tests against white, requiring very large text sizes (24px or 19px bold) to meet minimum AA standards. To improve accessibility, consider using a lighter shade of blue or pairing it with a very light color such as #FFFFFF, #F0F0F0 or #E0E0E0 for text and interactive elements. Providing sufficient contrast ensures readability for users with low vision or color blindness. Avoid using this color for critical information or calls to action without careful consideration of contrast. The use of text shadows or outlines can also help to improve contrast, but should be tested with assistive technologies to ensure effectiveness.
