Adjusting from the default color temp of a certain image is like changing the white balance settign on your camera before you shoot. If you shot an image under tungsten lights and your white balance was set to Auto it may not be just right. So you can do one of several things....
1. you can go into your editing program if using RAW and change your white balance setting.
2. You can use photoshop and change the hue and saturation.
3. You could slide the Color Temp setting to what the lighting temp would be. THis is the same thing you RAW program does when you change from auto to Sunny to Tungsten. If you use the color temp slider you can get a little more in between the hard setting. This comes in handy when you may have a mix of lighting.
Here are a few things that may help.
