#1905AB

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #1905AB, is a deep blue hue reminiscent of the pigment derived from the precious mineral lapis lazuli. This color evokes feelings of serenity, stability, and wisdom. In color psychology, blue is often associated with trust, loyalty, and intelligence. Ultramarine, being a darker shade of blue, adds a sense of depth and sophistication to these associations. It is a popular choice in branding, design, and art to convey trustworthiness, reliability, and a sense of calm authority. Its rich tone also makes it a visually appealing color for creating focal points and accentuating details. It should be handled carefully and combined with lighter colors in order to meet web accessibility standards.

The color #1905AB, also known as Ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its dark hue results in low contrast when used against a standard white background. This low contrast can make text difficult to read and interactive elements hard to distinguish. To enhance accessibility, it is crucial to use #1905AB with lighter colors that provide a high contrast ratio, ideally exceeding the WCAG (Web Content Accessibility Guidelines) recommended ratios of 4.5:1 for normal text and 3:1 for large text. Using a lighter background color such as #FFFFFF (white) is not enough, and a lighter color is needed to compensate for the dark color of #1905AB. Avoid using #1905AB for critical information or calls to action without careful consideration of its contrast against surrounding elements. Consider using tools to test color contrast and ensure compliance with accessibility standards.
