What I suggested is not a piece of software, it's an 'action' that is downloadable from Adobe's website that can then be added to the Actions palette in Photoshop. I had a look at DevonDiver's link and at a quick glance, the steps in it are similar to what the underwater action does... but far quicker as it's 'automated.'

I used to use the Underwater Action, but I found that it wasn't flexible enough to provide good results on the majority of photos, especially when there was a lack of original red pixel information.

You can get simularly good 1-step results simply by using the eyedrop sampler in Curves to designate black and white points in the photo. But if the red pixels aren't there, it will still look quite washed out, or can be color skewed.

Using the Channel Mixer is the only way to add the red pixel information, if it wasn't captured when you originally took the pic. That step cannot be automated well, because it is very individual to the photo.
 
The OP asked for a method that was easy and mentioned Picasa. I'm more than happy to be wrong, but I'm getting the impression that he does take 'snapshots' and merely wants them to look less blue when he shares them with friends, etc.

I just take pictures for fun to upload to FB or my Picasa albums (which is why I like the ease of the Picasa app). Olympus 1030sw waterproof camera, housing, and an underwater flash.

My pics are good if the subject is within flash range, but if greater than 18"....the result if very blue.

That Olympus camera does not give you the option to shoot in RAW file format, just JPG, so there is limited correction possible in PS.

There are many ways with PS to increase reds and decrease blues.

Going forward, your best bets for this camera's pic's are; external strobe, keeping the sun behind you, shooting at at least a small angle above horizontal, manual white balance.

Going forwarder, your best bet for pics you will like better is buying a camera that shoots in RAW. Then if the sun and angle advise above are followed, I find a basic WB import to PS, the Auto Color adjustment and the Shadows and Highlights adjustment often are all that is necessary.
 
Thanks for the action link. Sounds like it will work well with my photos too and I can tweak it. I agree, the photos should have some blue in them.
