If you are familiar with our Photoshop articles as well, you may remember the Color Variations feature. Once again we rely upon this command as a somewhat simpler version also exists in Photoshop Elements.
Click Enhance/Adjust Color/Color Variations and the above dialog appears. The image in the upper right corner will show the results of your changes. At the bottom, colors and lightness can be set in three steps.
1. First, you have to specify the lightness interval in which you want to adjust colors. Midtones is the first choice. It is generally recommended for pictures with normal exposition, such as this one. Shadows and Highlights are pretty obvious, too. Saturation affects the strength of colors. Select Midtones.
2. The Adjust Color slider allows you to specify the steps in which the adjustment happens. As we just want to remove a slight blueish color veil, we should choose size 1.
3. In the lower right corner, you can click small preview images that increase or decrease the levels of the different color ranges. They are:
Opposite to blue, reds are the weakest in this photo, so we clicked Increase Red to enhance them a bit. This brought warmth into the colors of the picture. The dominance of blues was restricted by clicking Decrease Blue. You can click a preview image multiple times to take more than one step in the adjustment.
