General Information about Ultramarine

The hex color code #000298, commonly known as Ultramarine, is a deep and intense shade of blue. In the RGB color model, it is composed of 0% red, 0.78% green, and 59.61% blue. This composition results in a color that is perceived as rich and luxurious. Historically, ultramarine was derived from the rare and expensive mineral lapis lazuli, making it highly prized by artists. Today, it is synthetically produced but retains its association with quality and sophistication. In color psychology, dark blues like #000298 are often associated with trust, stability, and authority. This color is suitable for applications where conveying a sense of reliability and professionalism is important.

The hex color #000298, a deep ultramarine, presents significant accessibility challenges, especially in text applications. Its extremely low luminance contrast ratio against white backgrounds falls far short of WCAG standards, making it difficult for users with visual impairments to read. When using this color for text, a very light color such as #ffffff or #ffff00 for the background is mandatory. Also, large font sizes and bolding can mitigate some of the contrast issues. In user interface design, this color should be used sparingly for decorative elements rather than crucial interactive components, or use a lighter tint as background. Thorough testing with accessibility evaluation tools is crucial to ensure compliance and optimal user experience for all users.
