I think the photographer used color to give this photo a warm, nice mood. Using warm colors, the effect of heat and comfort emanates from the photograph. I think they used a split tone to saturate the oranges in the photo.

Using cool colors and a dark filter, the photo creates a cold and icy feel. The dark blue of the water makes it look freezing and uninviting. It makes me feel nervous being out in the open sea. I think the photographer turned up the green saturation in this photo, and turned down the saturation in the sky.

The use of black and white makes the photo feel moody and barren, it looks like a place you wouldn't want to hang out at. I can tell there is really good technique in this photo to make it seem that way, because this is a photo of the Sydney Opera House. The Sydney Opera House has always been made to look exciting and welcoming, but the photographer managed to make it look like a dead zone!
