Remove the threshold adjustment and look for an area of your image that appears gray. Some of the walls appeared fairly close to white so I clicked on one of the brighter surfaces resulting in a significant improvement. For example, this shot of the Texas Capitol came out incredibly warm and needed to be cooled down. Even if you didn’t shoot something pure white in your image, try and identify a surface that should be close to pure white and use that as your correction point.

The software will automatically adjust your color balance in the image and ideally, remove any unwanted cast. Assuming you took a shot of something pure white or 18% gray, all you need to do is select the tool and click on the respective surface. The eyedropper tool can be found in both Lightroom as well as Camera Raw in Photoshop. This is by far the easiest and most obvious way to remove most any color cast. I was able to pick up the DataColor Spyder5Pro for less than a $100 and it has more than paid for itself over time. B&H sells color calibration tools as part of its Daily Deal Zone offers all the time. This is commonly overlooked by amateur photographers but incredibly important as the colors on your monitor are almost certainly not accurate. It should also be noted that all of this will all be in vain if your monitor is not properly color calibrated. These surfaces can provide a benchmark in post to properly measure the color temperature in a scene. Finally, before or after shooting a scene take a shot of something that is pure white or 18% gray, such as a gray card, as close to your subject as possible. This especially includes anything that is red or even the color of your shirt as the photographer. It is also important to avoid objects in your photo with strong, unwanted colors as much as possible as those colors will almost certainly be reflected onto your subject. White balance settings are directly tied to the overall color in an image therefore, slight adjustments can create large differences. This includes shooting in raw which provides leverage when adjusting white balance later on. First, you need to do all you can in camera to prepare for managing a color cast in post.
