readjust or start over, color balance mismatch

I have a series of three shots that were converted from RAW files, cropped, adjusted and saved as flattened PSD files for printing. Now, after the fact, I decided that I want to print the three together as a triptych. Unfortunately, I was just winging the original conversions and each one has a slightly different color balance. These are all the same subject in the same illumination, the color mismatch is an artifact. Each view by itself is fine, but together the first thing that strikes one is the color difference, doh!

I expect you'll tell me to start over and be careful to do each adjustment the same. eh? That's ok, just don't say it serves me right!

It serves you r...
Yup, I'd start over so they're sure to match up. We've all been there, some of us (me) many, many times before.

If the image is worth it, definitely start over.

There is a fuction in Photoshop called Match Color (Image>Adjustments>Match Color) that may do exactly what you want without you needing to start over. In the Photoshop Help file, type Match Color in the search window. About the fifth choice from the top in the results window you'll see something like " "to match the color in different images". Click on that and read how to use the Match Color command.

How far off are the images? If they are close and your revisions were extensive or time consuming, i would throw a color adjustment layer on top and play with tweaking them that way.

Another choice would be to go ahead and start over, do a curves adjustment layer on the first image to your liking then drag that same adjustment layer to the other images. This will apply the same exact color correction to all the images for your triptych.

Rod's suggestion of using color match is what I would try first though. Might as well give the easy fixes a run before the more involved ones eh?

Thanks for the replies. It turns out the Match Color procedure works! Cool, Photoshop does it all, I just don't know where to look. Starting with the raw files and doing the same adjustments doesn't give the same color. Apparently the light WAS different.
