So Data. As you requested here's the sprite and a screenie of how the colors turn out. I don't know if I'm just messing up but I've tried so yeah..

Quick fix for this I found out was to do this.
Take an already made bmp from the orginal device files and copy and paste your item in there.
Then save as in some other folder
And the colors should just be fine.
Works for me when I use vector art and colors into a bmp.
