[HELP] Custom spray gets weird

Whatever the colors I use in photoshop and whatever file format and settings my spray always gets black and seethrough? An example:

There I used white background and red text and styles, before i tried grey background or gradient stuff with orange text, the darker areas still got seethrough and orange got black and bad quality.

Like this:

Any suggestions to fix this? Never happened to me before. Really appreciated, thanks!

Fixed it anyway, no Nukk, not that it wasn't suppose to be transparent or blue background but thanks for trying to help.

It was suppose to be .gif 256 colors from photoshop no other format worked for me.
