What is a colorimeter?

A colorimeter is a tri-stimulus (three-filtered) device that uses red, green, and blue filters to mimic the way humans perceive color.

How does a colorimeter work?

A colorimeter works by shining an internal light source onto the surface of the sample. As the light reflects back to the device, it passes through three filters: red, green and blue. The filters distill these RGB values to quantify how our eyes will see that color.

What is a colorimeter used for?

Colorimeters are commonly used to calibrate computer monitors. They can also capture color and do basic evaluation for applications that don’t require tight color control. Because they are portable, designers like to use them to specify colors for use in designs.

Is a spectrophotometer the same as a colorimeter?

No, they are not. Colorimeters are not a replacement for spectrophotometers or formulation tools since they don’t account for metamerism, a common phenomenon that occurs when two colors appear to match under one lighting condition but not when the light changes. Spectrophotometers are more comprehensive in their measurement, as they measure and provide color data on the entire spectrum instead of just red, green and blue.


Colorimeters are tristimulus (three-filtered) devices that make use of red, green, and blue filters to emulate the response of the human eye to light and color.

Color management ensures that the colors captured by a camera are the same colors that will appear on the monitor, and the same colors that will print. Read our article to learn more.
