What is Sapphire Blue?

Sapphire is a saturated, mid-to-dark blue color that has a hint of purple or violet to it. It’s named after the precious gemstone sapphire which comes in a variety of blue shades. Sapphire gemstones have been prized for centuries for their intense blue hue. The first recorded use of “sapphire” as a color name in English was in 1200 AD.

There are a few different ways to describe the shade of sapphire blue:

  • Rich, deep, and saturated – Sapphire blue is much more saturated than light blues. It has a deep, jewel-toned appearance.
  • Blue with a hint of purple – What sets sapphire blue apart is its slightly purple or violet undertone. This gives it extra depth.
  • Similar to indigo – Sapphire blue is quite close to the color indigo. In fact, many use the terms interchangeably.
  • Darker than royal blue – Royal blue is moderately dark while sapphire leans closer to a midnight blue.

When it comes to technical specifications, sapphire blue is generally defined as:

  • Hex code: #082567
  • RGB: 8, 37, 103
  • CMYK: 100, 88, 41, 0

However, there are many variations of sapphire blue ranging from pale to extremely dark. The exact shade depends on how much violet is mixed in with the blue.

Where Does the Color Come From?

The sapphire blue color is derived from the mineral corundum, more commonly known as sapphire. Sapphire is a gemstone that forms in a variety of colors, but the most prized and valuable shade is blue. These blue sapphire stones showcase an intense, saturated blue hue.

The blue color in sapphires comes from the presence of trace amounts of iron and titanium within the mineral. Different levels of these trace elements result in the wide range of blue shades from pale sky blue to dark inky blue.

The most coveted sapphire stones from Kashmir and Myanmar have a rich, velvety blue color that leans slightly violet. This distinctive blue-violet shade was named sapphire blue after the gem that showcases it so well.
