In color theory, Prussian Blue is considered a cool color, often associated with feelings of calmness, trustworthiness, and authority. It lies between cyan and a darker navy blue on the color spectrum.

The hex color #003955, also known as Prussian Blue, presents certain accessibility challenges, especially in web design. Its dark nature means it requires careful consideration when choosing text and background color combinations. To ensure readability and inclusivity, it's crucial to use light-colored text on a #003955 background or vice versa. A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text (14pt bold or 18pt regular) to meet WCAG AA standards. Using tools like contrast checkers can help verify compliance. Also, avoid using color as the sole means of conveying information; supplement it with text or icons. Providing alternative text for images and ensuring proper keyboard navigation are crucial for users with visual impairments or other disabilities. Remember that sufficient contrast benefits all users, including those with low vision or color blindness.
