Color is a big component of setting the mood of a room, no doubt. A cool color such as a pale grey gives the sense of calm and a bright red gives the sense of high energy. Same goes for the color of art work.
I work in photography and have the capability to change the color of my images to create complete different looks. Take for example the below sailboat image:
The look is cool. I call this one “Spring Breeze” because I can sense a bit of a crispness to the air. This is the untouched image, direct from my camera. I then wanted to transform this image to something unique and different. Here is the result.
This is what I call “Summer Breeze”. It is the same file as the one above but here I have changed the colors creating an image that may not be realistic, which is ok, but it also changes the mood of the photo.
