General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #050A93, is a deep and intense shade of blue. Historically, the pigment was derived from the precious stone lapis lazuli, making it one of the most expensive and highly valued colors in the art world. The name 'Ultramarine' literally means 'beyond the sea,' referring to its origin from lands far east of Europe. In the RGB color model, Ultramarine consists of 2.0% red, 3.92% green, and 57.65% blue. Its high blue component is what gives it its characteristic deep blue appearance. Ultramarine is often associated with qualities like depth, stability, and authority, making it a popular choice in various design applications. The color is also known for evoking feelings of calmness and serenity, but its intensity can also suggest power and importance, depending on the context in which it is used.

The hex color #050a93, also known as Ultramarine, presents significant accessibility challenges, particularly in text-based applications. Its very dark hue results in extremely low contrast against standard light backgrounds, such as white. This makes it difficult for individuals with visual impairments, including those with low vision or color blindness, to read text rendered in this color. To ensure accessibility, it is crucial to use #050a93 with very light colors that provide a contrast ratio meeting WCAG guidelines (minimum 4.5:1 for normal text and 3:1 for large text). Failure to adhere to these guidelines can exclude a significant portion of users. It is also important to avoid using this color as the sole indicator for important information, such as links or error messages. Providing alternative cues, like underlines or icons, can enhance accessibility for all users, regardless of their visual abilities.
