About Ultramarine (#210395)

The hex color #210395, commonly known as Ultramarine, is a deep and intense shade of blue. It belongs to the blue color family and is characterized by its high saturation and relatively low lightness. In the RGB color model, #210395 consists of 12.9% red, 1.2% green, and 58.4% blue. Its CMYK values are 78% cyan, 99% magenta, 0% yellow, and 42% black. Ultramarine's deep hue evokes feelings of calmness, trust, and authority. This color historically comes from the costly pigment made by grinding lapis lazuli into a powder. Due to its high cost in the past, it was often reserved for paintings of special importance, like depictions of the Virgin Mary. The modern pigment can be chemically created so it is not as rare as it used to be. In color psychology, Ultramarine is associated with intellect, stability, and unity. It is often used in branding and design to convey a sense of reliability and professionalism.

The hex color #210395, a deep ultramarine, presents certain accessibility challenges, particularly in text applications. Its low luminance value of approximately 3% necessitates careful consideration of contrast ratios. When used as a background color, it requires a very light text color to ensure readability, ideally achieving a contrast ratio of at least 4.5:1 for normal-sized text, as recommended by WCAG guidelines. For larger text (14pt bold or 18pt regular), a contrast ratio of 3:1 is acceptable. Avoid pairing it with dark or muted text colors, as this will render the text illegible for many users, including those with visual impairments. In interactive elements, such as buttons or links, sufficient contrast is crucial for users to easily identify and interact with them. When using this color, it's important to test the design with accessibility evaluation tools and, ideally, with users with disabilities to ensure it meets their needs.
