It belongs to the broader family of blue colors, which are often associated with feelings of tranquility, stability, and wisdom. In color psychology, blue is known to evoke feelings of calmness, trust, and security. This makes Cerulean Blue a popular choice in various applications, from branding and web design to fashion and interior decorating.

The hex color #1f49b6, also known as Cerulean Blue, presents some accessibility considerations for web developers. Its relatively low luminance value means that using it as a background color requires careful selection of foreground text colors to ensure sufficient contrast. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. When #1f49b6 is used, white or very light shades of yellow or green would be good options to provide enough contrast. It's crucial to test the color combination with accessibility tools to confirm compliance and ensure readability for users with visual impairments. Overlooking contrast can exclude users and result in a negative user experience. Also, avoid using color as the only means of conveying information; provide alternative cues like text labels or icons.
