Hi,
DBT,
welcome to
RP!!
In my opinion, the easiest (and cleanest) way to do this, is what
KR1156 said... meaning, playing with the Layers' blending... no selections and no masks!!!
I work with Photoshop, but I think you can do the same in
PSP ...
First, you should change the mode of your original from '
Index' to '
RGB'...
...if you want to put your logo on a black background, the easiest way is to duplicate the background and 'invert' the duplicate ... (a negative copy of your original...) (

If you'd rather use colours or a different background, here is what to do:
- Working with the original version
- Duplicate your background
- Change the blending of the duplicate to Multiply
- Create a new empty Layer between background and duplicate
- Fill the empty layer with the colour of your choice
- Working with the inverted version
- Same procedure as with the original ... but change the blending of the duplicate to Screen

You can use a gradient to fill the empty layer in between or put a completely different background ... (
