Colour image did not show much colour, indeed. A clear option would have been the saturation increase, until some (in my opinion) unrealistic colours could be obtained, as frequently seen in commercial postcards. 

Instead, I decided to produce a black and white image, concentrating in the hill and tree textures.

Then, I made an analysis of the colour channels, Green channel showed a wide latitude, from the brightest tones to the shadows in the tree; blue channel was, in this case, too soft and did not bring in much information. Then, red channel, as opposite to green, included much contrast information in the hill texture.
