Blue is often used in web design for its calming effect and is believed to convey trust and professionalism. Websites with a blue color scheme may include elements such as headers, navigation bars, buttons, and background designs that incorporate blue hues. It is important for designers to consider the context and target audience when choosing a blue color scheme to ensure it aligns with the brand identity and user experience goals.
