Sapphire blue (#0F52BA) is a striking, deeply saturated shade that takes its name from the precious gemstone. This rich blue combines 5.9% red, 32.2% green, and 72.9% blue, creating a color that has captivated designers since it was first recorded as an English color name in 1430.

Psychologically, sapphire blue evokes tranquility, wisdom, and spiritual depth, making it perfect for brands seeking to convey trust and sophistication. In design, it pairs beautifully with complementary colors like gold and coral, or harmonizes elegantly with analogous blues like navy blue and royal blue.

For digital projects, sapphire blue works exceptionally well as an accent color against neutral backgrounds like light gray or ivory. Its high saturation (85%) and moderate lightness (39%) ensure excellent readability while maintaining visual impact, making it ideal for buttons, headers, and brand elements that need to command attention without overwhelming the design.
