#190593

General Information about Ultramarine

The color #190593, also known as Ultramarine, is a deep shade of blue residing in the blue-violet segment of the color spectrum. Its hexadecimal representation, #190593, indicates its composition using the RGB (Red, Green, Blue) color model, where Red is 10.2%, Green is 2%, and Blue is 57.6%. Ultramarine is historically significant, originally derived from the precious gemstone lapis lazuli. This made it one of the most expensive pigments used in painting, often reserved for depicting important figures or elements in religious art. The color is associated with qualities such as depth, stability, and wisdom. In modern color psychology, dark blues like Ultramarine are often used to evoke feelings of trust and security, making them popular choices for corporate branding and website design. Its high blue content also lends it a calming effect.

The hex color #190593, a deep ultramarine, presents significant accessibility challenges, especially in text-based contexts. Its low lightness value (YIQ: 11) necessitates extremely light foreground text colors to achieve sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using #190593 as a background with standard black or dark gray text would fail miserably, making it difficult for users, especially those with visual impairments, to discern the content. Therefore, if employing this color, careful consideration must be given to pairing it with very light hues like white (#FFFFFF) or pale yellows to ensure compliance with accessibility standards. Additionally, providing alternative visual cues, such as underlines or icons, can further enhance usability. The context in which the color is used is also critical; using it for decorative purposes rather than essential information lessens the accessibility burden.
