If you have read many of the reviews on this site we have always tried to provide some education about the different light technologies used in projectors and how those different technologies change the way we perceive color. DLP projectors because of the color wheel technology used can tend to have a hard time with primary colors. They can render these primary colors when playing video without a problem, but when a true yellow or a true red is used in a static image that might be in a PowerPoint presentation DLP projectors tend to make those colors take on a mustard like appearance. At least in the the yellow colors case. Red can tend to turn a slight orange.
To remedy the problems described above a user has to generally enter the menu system and play with the color settings until the colors look more correct. In most cases accurate colors can be achieved by lowering the brightness a bit. It's slightly different for each projector. Most won't notice this color issue to be a problem, but if you are particularly picky, this might annoy you.
The HX300G produced some pretty nice reds and yellows. Looking at the spreadsheet in the previous section will give you a pretty solid idea how the projector looks right out of the box. No adjustments were made to the image. I was quite impressed that it had the vibrance that it did without that annoying mustard color that can happen with yellow.
