Natural green

In Northwestern Portugal, Autumn does not bring very intense colors. Except for vineyards and some trees, a lot of the vegetation (pines and eucalyptus, for instance) remains green throughout the year. I long for those New England's Autumn colors, with unbelievable intense oranges, reds and yellows. I'll have to go back there some time (when I retire?...).

I've always thought that green foliage (around here at least) alone does not work well in photographs. I find it to be a cold, a bit unpleasant, color. The photo below was "saved", I think, by some patches of reddish-brown in the water, a few leaves and the roof top. These bring some warmth to the image.
