Even in theatre mode, the Epson 710HD projector is just a bit cool, that is, a little thin on reds, but it is slight. Calibrating the Epson projector gets you about half way from this starting point, to where you want to be - which is all numbers around 6500K.
All considered, Theatre mode produces a very nice, and reasonably well balanced grayscale balance (color balance). That is, Red, Green, and Blue are all in the right proportions for the most part, without any glaring issues such as too strong greens. Calibrated, this projector is even better when it comes to color.
