Look for two lumen specs. Color brightness, different from white brightness, indicates how bright projected colors are.
Epson projectors have up to 3x Brighter Colors* than leading 1-chip DLP projectors. In a recent study, it was also found that 9 out of 10 respondents prefer images from Epson 3LCD projectors.1Watch Video

These two images from similarly priced projectors have comparable white brightness lumens, but the noticeable inequality in image is due, in large part, to the difference in color brightness lumens.Compare Color Lumens of Projectors

Color Brightness: What It Is, Why It Matters
In an article from PCMag, award-winning writer and expert in imaging technologies, M. David Stone, explains color brightness and its relevance.Read Article
Understanding Projector Lumens
Brightness is measured in lumens, but there are 2 specs. When asked, 79% of projector buyers surveyed think a single lumen number means both white and color brightness.3 It does not.
Many manufacturers provide only one specification which states the white brightness (White Light Output). If color brightness (Color Light Output) is not listed, the actual number may be as low as 1/3 of the provided spec. Epson lists both specifications.View Color Brightness PDF
Color Brightness Explained
Vibrant color is important, since 86% of content projected includes color.3 If color brightness is low, colors can look dull or dark, skin tones are reproduced poorly and important details can be lost.Watch Video
Epson's Advantages over 1-chip DLP Projectors
Epson Projectors have up to 3x Brighter Colors
3LCD technology uses 3 chips to deliver vibrant, true-to-life and consistent images. Epson projectors use 3LCD technology that has no color wheel and therefore does not force a trade-off between white and color brightness.Watch Video: How 3LCD Technology Works
A Nationwide Study Found that 9 out of 10 People Prefer Images from Epson 3LCD Projectors
Radius Global Market Research conducted a study to objectively learn which projection technology – 3LCD or 1-chip DLP – delivers preferred images. Nearly 900 participants across the US were shown the same image projected side by side and asked which they favored, and 9 out of 10 respondents, preferred images from Epson 3LCD projectors.1
The Color Brightness Specification
The New Standard
The color brightness specification is an authoritative standard recently developed by the International Committee for Display Metrology (ICDM), and this widely accepted standard measures the projected brightness of red, green and blue light.
3LCD Technology Explained
3LCD Engines send light continuously (not sequentially). All colors are available all the time. In 1-chip DLP, only one color is available at a time, resulting in lower color brightness and system efficiency. Some systems use a white segment to boost white brightness, this approach is proven to degrade color accuracy.

Hundreds of different projector brands and models have been tested, and the color brightness ratings are listed.
What the Experts Say About Color Brightness
Color in Communication: Color Light Output White Paper – Michael Goldstein
Goldstein writes an informative paper about the Color Light Output specification and how it offers users the ability to quickly, easily and accurately evaluate color performance between competing projector models.View White Paper
Color Light Output in Projectors and the New ICDM Color Brightness Standard – Peter H. Putnam
This in-depth look at the public's growing awareness of color quality in technology explores how projector technology has matured - moving away from the emphasis on white lumens and toward including color lumens. Putnam writes that a well-designed projector should produce the same level of brightness of a full-color image as a white image.View White Paper
* Compared to leading 1-chip DLP business, education and home entertainment projectors. For home entertainment, Epson 720p projectors are 3x Brighter; Epson 1080p projectors are consistently 2x and up to 3x Brighter. Based on NPD data, July 2011 through June 2012. Color brightness (color light output) measured in accordance with IDMS 15.4. Color brightness will vary depending on usage conditions.
- Among people who had a preference, 9 out of 10 preferred images from leading Epson projectors over leading 1-chip DLP business and education projectors. Leading projectors selected according to NPD data as of July 2013. Based on independent U.S. research conducted by Radius Research (July 2013).
- Specifications for color brightness and white brightness are provided by many manufacturers and published by ProjectorCentral.com. These manufacturers do not provide a color brightness specification for these models. This data was obtained from independent third party laboratory testing of a unit according to the international standard for measuring color brightness, IDMS 15.4.
