Now out: Temperature Variations CS2 that works with Photoshop CS and Photoshop CS2. (The image processing hasn't changed, so if you're still using Photoshop CS, you don't need to upgrade; the only significant change is to file i/o that uses the ..\Presets\Scripts folder to store settings.)
Temperature Variations: an easy way to adjust the ambience of your images by adding warmth or coolness. The standard version of the script comes with the Warming 81 and Cooling 80 filters. The CS2 version adds Warming 85 and Cooling 82. The filters are arranged in pairs for a set of eight treatments and according to the settings you select, you will see four different filter strengths.

This cut-out from the dialogue window shows the Treatments and Extras panel. There is one filter per treatment row at different strengths. This is changed by using the radio buttons at the bottomof the Extras panel. Low Range runs from 10%-40%, medium from 40%-70%, high from 70% to 100% and wide from 20% to 100%. The labels on the treatments will change to reflect the selected setting,
The CS2 version has an additional button to switch between warm and cool filters. You can run previews for any filters, but you can only apply treatments for the active filters. The Plus version of Temperature Variations also has the additional features described in Plus What?
