As described in , the tristimulus colorimeter has features such as comparatively low price, compact size, superior mobility and simple operation. Colorimeters can determine tristimulus values easily. However, a colorimeter is not appropriate for complex color analysis such as metamerism and colorant strength.
A spectrophotometer has high precision and increased versatility. It is suitable for more complex color analysis
because it can determine the spectral reflectance at each wavelength.
However spectrophotometers can be more expensive than colorimeters.
Always consider how accurately each color must be measured before selecting the type of instrument
to use in a specific application.
