Ya soz just read it back to myself lol and I see what you mean.

No worries I have sorted it not, its just because when I was setting the colours in photoshop they weren't pure black and white if you see what I mean, for instance the white was not at 255 in the RGB colours.

I have been drawing smoke particles in photoshop and basically was messing up the colours, but have it now so all is good lol.

Cheers anyways.
