The low saturation and relatively dark nature of this color give it a calming and subdued appearance.
The hex color #003B64, also known as Astronaut Blue, presents some accessibility challenges. Its relatively low luminance value results in a low contrast ratio against white backgrounds, potentially making text 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 to meet WCAG AA standards. Using this color for text or important UI elements requires careful consideration of the background color. Pairing it with a very light color like #FFFFFF or #F0F0F0 can improve readability. Testing with accessibility tools is crucial to ensure compliance. Also, consider providing alternative color schemes for users who need them.
