Just wanted to say thanks for this, I've been tempted to soft mod several times in the past but have stuck with my wiikey 1 because I didn't really understand what softmodding was doing.
Had a look at this app and thought sod it, don't try and understand it, just follow the instructions...
I tried all the colours in my black lite and decided the best looking was actually the white one. The contrast looks good and the slight misfit is not a bother as it doesn't look like it's trying to hide.
