Yes. JPEG files have less white-balance flexibility than RAW, but you can usually correct a mistaken Tungsten setting well enough in Photoshop workflows.

Two practical options mentioned are:

1. Adobe Camera Raw: Open the JPEGs in Adobe Camera Raw (for example via Bridge), then adjust the color temperature/white balance controls just as you would with a RAW file. If many images were shot under the same light, you can apply the same correction to all of them in a batch.

2. Levels / neutral-point correction in Photoshop: Use Levels and the white, black, or especially gray/neutral eyedropper to click an area that should be neutral gray or white. Photoshop will rebalance the color channels to reduce the cast. You may need to fine-tune per image.

The easiest method is whichever gives you a believable neutral reference in the photo. If all the shots were made under the same lighting, batch-applying one correction can save a lot of time.
