The hex color #150794, also known as Ultramarine, is a deep and rich shade of blue. In the RGB color model, it is composed of 8.24% red, 2.75% green, and 58.04% blue. This combination gives it a distinct and intense character. Ultramarine has a long history, dating back to ancient times when it was derived from the precious stone lapis lazuli. Because of the historic extraction process of the pigment, it was a pigment that only the rich could afford. It was widely used in Renaissance paintings and is often associated with royalty and spirituality. The color's deep hue is perceived as trustworthy and stable. In modern color psychology, ultramarine is often linked to knowledge, power, integrity, and seriousness. It is popular in branding and marketing materials to convey a sense of reliability.

The hex color #150794, a deep ultramarine, presents significant accessibility challenges. Its very low luminance value means that text rendered in this color against a white or light background will have extremely poor contrast, making it difficult to read for users with visual impairments. According to WCAG guidelines, the contrast ratio should be at least 4.5:1 for normal text and 3:1 for large text. #150794 fails to meet these standards against most light backgrounds. Therefore, it is crucial to use a much lighter color for text or interface elements on top of #150794, or conversely, a much darker color for backgrounds when using #150794 as the primary color. Testing with accessibility tools is highly recommended to ensure compliance and optimal readability. Also, avoid using this color for crucial information-carrying elements without providing sufficient contrast.
