Its relatively low brightness makes it a suitable choice for backgrounds, provided that appropriate contrast is maintained with foreground elements.

The hex color #105080, also known as Chathams Blue, presents some accessibility challenges, particularly when used as a background color for text. Due to its relatively low luminance, it requires careful consideration of the foreground text color to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When pairing #105080 with text, lighter colors like white (#FFFFFF) or very light shades of yellow or green are generally needed to meet these accessibility standards. Tools such as contrast checkers can be used to verify the contrast ratio between the background and foreground colors. Insufficient contrast can make content difficult or impossible to read for users with visual impairments, thus negatively impacting usability. Using this color for decorative elements where readability is not a concern poses less of an accessibility risk.
