#190494

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #190494, is a deep, intense shade of blue. It is a color that evokes feelings of depth, stability, and intelligence. Historically, the term "ultramarine" originates from the Latin "ultramarinus," meaning "beyond the sea," as the pigment was originally derived from lapis lazuli imported from Asia. Lapis lazuli, a semi-precious stone, was ground into a powder to create the pigment, making it highly prized and expensive, often reserved for important figures and religious art. In modern times, ultramarine is synthetically produced, making it more accessible for various applications. Its unique hue is characterized by its slight reddish undertone, which distinguishes it from other blue pigments. In color psychology, ultramarine is associated with trustworthiness, loyalty, and authority, making it a popular choice for branding and corporate designs aiming to convey these attributes. Its vibrant and rich nature makes it a versatile color for use in digital and physical design projects.

The hex color #190494, also known as Ultramarine, presents significant accessibility challenges, particularly in text-based applications. Its low luminance value means that it offers insufficient contrast against commonly used light backgrounds like white or light gray. This lack of contrast can make it difficult for users with visual impairments, such as those with low vision or color blindness, to read text rendered in this color. To ensure accessibility, it's crucial to pair #190494 with a very light color for text or other important visual elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text. Therefore, web developers should carefully assess the contrast ratio when using this color and provide alternative color combinations if necessary. Tools are readily available online to check contrast ratios and ensure compliance with accessibility standards. Furthermore, avoid using this color alone to convey critical information, as colorblind users might not be able to distinguish it effectively.
