Altering a DDS file

[Contro]

Hi Guys!

I recently downloaded a new UI setting (so that the frames, and pretty much everything else, was a shade of purple). This had obviously been done by adding a hue or what not, but the problem I have is that the arrows, which appear above mobs which are either stronger or weaker than they appear, have also been dimmed slightly with a purple hue.

I have got the plugin for photoshop which allows me to alter DDS files, but when I try to drag the original set of arrows over the hued versions (from the original file to the new updated file), the resulting image in the game has an arrow, which I'm sure was the correct colour, but are encased in a black square (one square per arrow).

I'm assuming it's something to do with the way I am saving the DDS file, but the NVidia save option has so many different parameters, I just don't know which one would provide the desired resuilts (or even if it's just something I need to do in Photoshop).

Please help! Thank you very much in advance!
