It is considered a cool color and can evoke a sense of tranquility and seriousness.

The hex color #2B3170, also known as Astronaut, presents certain accessibility challenges, especially when used as a background color for text. Its relatively low lightness value (around 15%) means that text needs a high contrast ratio to be legible. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text to meet AA compliance. Using a light color like white or a very pale yellow for text on an #2B3170 background would generally meet these contrast requirements, making the content accessible to users with visual impairments. However, caution should be exercised when pairing #2B3170 with mid-tone colors, as the resulting contrast may not be sufficient for readability. It's advisable to use contrast checking tools during the design process to ensure compliance with accessibility standards.
