Royal blue (#305CDE) is a vibrant, sophisticated shade that commands attention while conveying trust and professionalism. This rich hue sits perfectly between standard blue and navy blue, offering more saturation than navy but maintaining its regal dignity.

Named after Queen Charlotte in the early 19th century, royal blue has evolved from an exclusive aristocratic color to a digital design staple. With RGB values of 48, 92, 222, it creates striking visual hierarchy in user interfaces and branding.

In design applications, royal blue excels as a call-to-action color, building user confidence through its associations with stability and reliability. It pairs beautifully with complementary gold for luxury brands, or neutral tones like champagne and ivory for balanced layouts.

For digital accessibility, ensure sufficient contrast when using royal blue for text or interactive elements. Consider similar shades like cobalt blue or sapphire blue for palette variations that maintain the same commanding presence.
