General Information About Ultramarine (#1505AE)

The color #1505AE, also known as Ultramarine, is a deep, rich shade of blue with a hint of violet. It derives its name from the historical pigment made from ground lapis lazuli, a semi-precious stone. In the RGB color model, it is composed of 8.24% red, 2.0% green, and 68.24% blue. In the CMYK color model, it consists of 88% cyan, 97% magenta, 0% yellow, and 32% black. Ultramarine is often associated with royalty, wisdom, and spirituality. It's a versatile color that can evoke feelings of calm and tranquility, yet also possesses a certain intensity and power. Its use can range from creating a sense of sophistication and elegance to adding a bold and striking element to designs.

The color #1505AE, also known as Ultramarine, presents some accessibility challenges, particularly when used for text or interactive elements. Due to its low lightness value, it offers insufficient contrast against a white or light-colored background, potentially making it difficult for users with visual impairments to read or interact with the content. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. #1505AE often fails to meet these ratios with standard light backgrounds. To improve accessibility, consider pairing it with a very light color such as white, or lighter shades of yellow or green to ensure sufficient contrast. Alternatively, using #1505AE sparingly as an accent color rather than for primary text elements can help mitigate accessibility concerns. Tools like contrast checkers can help verify compliance with accessibility standards.
