The Q7 has six named picture modes, plus User, and User1. The image player here shows all of them in action, and you can read the mode name easily on the pull down menu captured in each photo.
Most of the modes have some pretty good color. Not exceptional color by any means, not serious home theater projector color, but more than adequate for all but the most color accuracy demanding presentations. Bright mode, is the brightest, and is apparently 'native" mode, with the usual helping of extra greens and yellows that is typical of the brightest mode on most projectors. Save Bright mode, for when you need every last lumen. Presentation, Game, TV sRGB, and User all look pretty good, but different. Some are cooler - more blue than others. In this sequence User1, the only one that lets you adjust Brilliant Color, is a bit red-orange, from my playing around. User1 provides the most ability to adjust the color, but it's a long way from ideal with the settings I was playing with.
If you are presenting, I suggest you look at your presentation (or part of it) though two or three of the modes, and pick the one you think is the best of the group.
There is one issue worth noting, and that is color saturation. First of all, LED light source projectors seem to tend to have a wide color space, and often look over saturated. Unfortunately, unless you are using low res sources, such as the composite video, you can't adjust the color saturation. As a result, the skin tones and colors in our test image all look at least a little over saturated. User1 also has access to a basic RGB adjustment, which I was playing with to reduce saturation, but I didn't spend enough time to reduce saturation and have good color in User1.
From a practical standpoint, a projector of this brightness, used for business, education, or even digital signage applications, is often dealing with ambient light, so a little extra saturation will help cut through the ambient. Still, I'd prefer to see a working Color Saturation control when working with HDMI and Computer sources.
