Making Selections Based on Color and Focus

Before
After

I was able to change the the color of the toothbrush as well as the background into a more saturated color by selecting the desired shared color within the entirety of the image. This in turn is able to change the tone of the photograph taken as I am able to darken or lighten colors that I want as well as being able to focus in on certain subjects within the image. I was able to make the toothbrush stand out more by changing the color of the tooth brush and the toothpaste, draining its color almost entirely, whilst the background adds  more emphasis on the subject of the photo. This technique can be used as a means to change large portions of background colors to either lighten or darken the photo, thus changing how colorful or monotone it is.
