Gray is a neutral color that falls between black and white on the color spectrum. There are many shades of gray that range from a pale silver to a dark charcoal. Some shades of gray can take on subtle color casts, like red, green, or blue. A bluish gray is a cool-toned shade of gray that has a subtle blue undertone.
What Causes the Bluish Tinge?
The bluish tinge in certain shades of gray comes from having more blue pigment or light wavelength mixed into the neutral gray color. Here’s a more technical look at what causes gray to take on a blue cast:
- Pigment Mixing – When creating a bluish gray paint or dye, more blue pigment particles are added into the neutral gray base. The more blue pigment, the stronger the blue tone.
- Light Wavelengths – On a computer or TV screen, gray is made by mixing red, green and blue light. Increasing the amount of blue light makes the gray take on a bluer tone.
- Natural Light – The quality of natural light can alter gray’s appearance. Cool northern light tends to bring out bluish undertones compared to warm southern light.
So in summary, a bluish gray arises whenever there are more blue wavelengths or pigment mixed into the neutral gray base. The result is a chic, modern gray with a hint of blue.
