Selecting by transparency?

[Phillip]

I'm trying to change a template from black, to a shade of blue. Rather than just filling everything in and having it look choppy, I'm selecting each pixel with the global Magic Wand and matching the exact transparency. Is there a more efficient way to do this? A plugin, maybe?

Have you tried my Color Balance plugin?

Or use the Recolor Tool    It preserves the subtle shades when recoloring.

Sorry, BoltBait, but the pack was just too difficult to install. Some sort of errors I didn't wish to navigate. I did, however, find luck with the Recolor tool.
