Projector Buyer’s Guide to 

Color Brightness by Model

Projector buyers should proceed with caution. 

Derived when presentations consisted of a black 

font on a white background, the old lumens metric 

only measures white light. Lumens, or brightness, 

tells the projector buyer little about the brightness 

of colors in photos, videos or graphics.

Fortunately, a newer metric gives projector buyers 

a measurement for the brightness of colors. Color 

Light Output, or more simply Color Brightness, 

quantifies the brightness of Red, Green and Blue; 

the primary colors of light.

The photograph below shows two projectors setup 

side-by-side, set in their brightest mode. Both offer 

similar resolution, price and white brightness levels.

The projector on the left exhibits low Color 

Brightness; only a fraction of its white brightness. 

The one on the right shows equal amounts of Color 

and White Brightness. Colors on the right are much 

brighter, providing more impact.

This document starts with a listing of projectors 

where the manufacturer specifies both White and 

Color Brightness. Second is a table containing 

projectors measured for their Color Brightness level 

by a 3rd party laboratory because the manufacturer 

did not specify the color brightness.

Insist on brighter colors. When selecting a 

projector, consider both the brightness of White 

as well as the brightness of Color.
