Color Accuracy
Good color accuracy overall, with smooth color response curves. The color gamut is a little inaccurate, though.
Color Temperature (10.00)
A good projector produces a clean, bright white and keeps it that way: the color temperature of the white should not change as the whites dim in intensity. If they do, you’ll see colors in certain shades of gray. The HD66 did well here: we saw only a very slight shift in the color temperatures that only became visible with the darker shades of gray.
| Color Temperature |
|---|
 |
RGB Curves (7.40)
To accurately reproduce subtle color changes, a projector has to offer a nice, smooth color response. The HD66 did well here: the response curves for red, green and blue were very smooth. The only issue that we found was that the red peaked rather early, which could mean that some highlight details of red objects get a little lost. This means that some bright red objects (such as uniforms) might look flatter than they really are; the subtle changes in brighter colors will be lost.

Color Gamut (2.93)
The colors that are present in a high definition color signal are defined in a standard called Rec.709, so a good projector will stick to this. We found that the HD66 was a little off here: the three primary colors were all slightly too far out, which could make colors look a little more intense than they are intended to look.

Below are the color co-ordinates for the Rec.709 standard and the ones that we measured off the screen.
