General Information about #2A3671

The hex color #2A3671, often referred to as "Astronaut", is a deep, muted shade of blue-purple. It belongs to the family of dark, cool colors and evokes feelings of sophistication, stability, and depth. In the RGB color model, it is composed of 16.47% red, 21.18% green, and 44.31% blue. This color is commonly used in design to create a sense of professionalism and trustworthiness. Its hexadecimal representation makes it easily usable in web design, graphic design, and other digital applications. The color is perceived as calming and can be used effectively to create a relaxing atmosphere. Due to its dark nature, it is important to consider contrast when using this color with text or other elements.

The hex color #2A3671, also known as Astronaut, presents some accessibility challenges, particularly for text and interactive elements. Its relatively low luminance of around 6% means that it requires very light text (white or near-white) to meet WCAG (Web Content Accessibility Guidelines) contrast ratios. Using dark or moderately dark text on this background will likely fail accessibility checks, making the content difficult to read for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Designers should carefully test color combinations using tools to ensure compliance. Consider using this color sparingly for purely decorative elements or pairing it with much lighter shades to ensure usability for all users. In situations where #2A3671 is used for interactive elements like buttons, ensure that the hover and active states provide sufficient contrast as well.
